Has anyone found any good websites for late 70's glastrons? Most seem to cater to 1950's and 60's vintage boats.

Stickman, I have a 77 CVX20 that I restored in 1990, in 95 I replaced the 460 Ford with a 468 Chev,I am running a b impeller and hyd. place diverter, this big old boat still turns heads and will run a hole in the wind.

I have a 76 CVX 20' with a 460 over 60 and minor head work done with performer rpm cam and a weind stealth. I have an A and B impeller I am running the A now. It is a real head turner and pretty fast for what I paid for the boat. The only site I know of devoted to carlsons is classicglastron.com

My 78 CVX-20 Deluxe is still a project. The new 460 longblock is ready to go. MSD billet distributor. Still need to pick a manifold and carb. Jet is rebuilt with stock impeller. Current project is replacing the floor that got soft due to hidden water in the bilge. It rotted from the inside out! Revised floor will have an access hole to make sure all the water gets out.
So anyway, I look at sites and read about other's boats until this one is done. Thanks for the input.

Lots of people do not remove the rubber plugs that are in the engine compartment make sure these are out!

Stickman, your project sounds like mine when I bought it, "LAKE READY", after redoing the motor, replacing the floor, rebuilding the seats, and the upholstery, carpet, clearing of the original metalflake, & several other item's like the fuel tank, I found out that I had bought a good trailer, because that was the only thing I didn't have to work on, but' I am very proud of the boat and it looks just like it left the factory, so keep the faith, it is a worthwhile project.

Yes, I found the plugs after I got the engine out. They are still not the best solution because the openings on mine are about 1 1/2 inches above the bottom of the bilge. Some water would always remain. I think an access panel and a wet/dry vac would make double-extra sure.
I had to redo the tank as well. Good news is I don't need to clear it. Gelcoat still shines.

Hi guys !!
This will be my first post, as a new cvx owner my story sounds alot alike, floor gone engine shot interior destroyed but a good project just the same . I was hoping someone could give me the performance capabilities of the cvx20 ...top speed tricks
etc.I have read all that i can find but it seems that there is not a lot of good information on the cvx20 jet. Any comments good or bad would help all of us Carlson owners.

The CVX 20' that I have has a 12JE pump and a 460. The engine has about 400-450hp place diverter new Aggressor "A" impeller all in all pretty stock pump. I turn about 5100 RPM's and that puts me to about 68. My goal is to hit 75-80. I am going to do some head work and stealth manifold. Hope that helps me a little?

thanks Jesse!!!
that is exactly what I was looking for.My cvx20 is a 1979 that came up from Fla.I have a 1969 429 being rebuilt at the engine shop with 10.5:1 flat tops a "little" head work on the exhaust side, mild cam,performer rpm intake ... not sure on carb size yet, with msd distributor and a cheater NOS kit .The pump is berkley 12JF with the electric trim , and what I assume is an A impeller(not really sure)I have been reading all I can but it is so much better to here "real world" information does you boat still have the fuel tank in its original position in the bow? what kind of fuel milage(how long does 27 gallons last on average)do you have a porpusing problem at low speeds ? and finally on last question ( for now http://free.***boat.net/ubb/smile.gif ) how does that hull design work in rougher water?? I live in Nova Scotia and the river leads to the ocean would that hull design live in a bigger swell??

I have a 78 cvx 20 with a 460 and 12JE pump.I had the pump rebuilt last year with an A impeller.The boat ran 67 at 5000rpm last year until the engine expired. Im currently building a new 460 with 11.2comp. a healthy solid lifter cam.I had the heads ported and am using a offenhauser port o sonic intake with a 750dp on top.Hope to see low 70s with this combo,but Ill have to wait a few more months to see.One thing I have noticed about my boat is that it does not like rough water,but rung great when it is smooth. Good luck with your project.......

quig, about the rough water, I have had the same experience as h2oboat, the carlson prefers smooth water over big swells and rough chop, not that it wont take it, it is just not comfortable to ride in on larger waves, mine will run in excess of 70 mph, as soon as the weather warms up here I will check mine with a gps, since I put the badass 468 in it, and as for the question about the fuel tank I found that it is simple to get an exact replacement that is a pvc or some composite material than to mess with the original metal one, and the 27 gal. tank shoul run you to the next marina,LOL, it all depends on your right foot, mine is heavy. Y'all Have a Great Holiday Season.

high 60's low 70's oh my!! http://free.***boat.net/ubb/wink.gif that is right where I had hope to end up at ... but by the sounds of things if everything is working correctly I will be starting there waahoooo!!! . hey pgf127rt do you know any companys that are making the composite fuel cell. I would love to replace the steel tank to remove some weight (and the rust inside),also for everybody, does the cvx have a problem with hook in the hull .I had hoped to just repait the top portion of the boat but while the engine is out I dont want to take a chance and miss something should I be concerned??

I have a 76' CVX 20 just got it in the fall. It has a 460 w/a Berk JE. Edelbrock torqer intake, Hardin Exhaust, Little ity bity 600 dp carb (750 on the way).I only had a chance to take it out twice after i bought it. Mine was in decent shape...Seems like a good motor(knoch on wood)No smoke. Just had a little rust. The intake manifod and Logs needed a little Love. Interior was good, Paint not so good, doesn't look bad in the water. I also have a rusty gas tank. Can anybody e-mail me pics of ther Glastron???

12-22-2001, 08:23 AM
another question for the group... what is the good the bad the ugly on the berkley E & F jets what makes them different and what berkley is the best to have for all around performance ? I also would love to see some cvx20 pics I will post mine as soon as get some

pgf127rt
12-23-2001, 07:26 PM
quig and antrant, I will get you the name of the supplier for the composite tank tomorrow, I think it was from Eddie marine but I am not sure the metal on that came with my boat had slabbed the rust so bad it wouldn't allow the fuel to come out never had a problem in 11 years, i will get some pix of mine, however the silver one on Classic Glastrons is the spittin image except for the place diverter and the 468 chev. it is a strong motor with an 850 annular discharge dp on a victor jr. sitting on a set of square ports with large stainless valves and comp cam, springs, and hyd lifters,it has a comp 9000 ignition and a berkley pump with a B impeller, spins about 5600, and loves Bajas, but if they out run me I will go back and get the Hondo Flat, with the bad Ford and blow them away.

I believe the E and F pump are the same, but the F pump has a jetovator.They are insert type pumps.My knowledge of pumps is limited,but growing. I do not thing the E and F pumps can support a 100 mph boat,but seem to work fine in the 60 70 mph range.Hope to push that to the mid 70s in a few months.My 78 cvx20 is the original metal flake blue.Ill see if the I can get someone to scan a picture so I can post one.No promises. MERRY CHRISTMAS TO EVERYONE........

I had a 77 cvx 18. For all you carlson guys that haven't replaced your flooring the flotation foam under the floor weighs about 200 pounds by now. Boy was that boat fun. When I sold it top speed was in the low 90's. Boat rode like it was on rails. Real screamer.

I have another question regarding rpm and the jet pump... with my 10.5:1 429 and hydralic cam ( that is not over .500 lift) I am expecting about 420-465 hp at or around 5400 rpm . Can anyone tell me if that is too much for an A impeller?? I was hoping to not take the pump apart this year( as I have repaired or replaced everything else http://free.***boat.net/ubb/biggrin.gif)... are there any tell-tale signs the the pump is worn out? visually the impeller seems to be in pretty good shape no real big hacks or scars but, can I tell anything more without taking it apart or a water test to see if it is spinning out??( this boat has been out of the water for about 5 years!!)
the floor and fuelcell mount are done!! now I am on to the engine bay to replace all the plywood there too!!

Quig,it sounds like your pump may be a little loose.Last year my 460 was spinning an A impeller 5000.The motor had dish pistons with ported dove heads,comp 292cam and 750dpcarb.From previous posts i have gathered it would take well over 500 ponies to turn a A impeller 5400RPM.Just my 2pennies worth.

Quig - Long story Bought the boat with stock FORD 302 power 188 hp-top speed was 51 mph. Boat wouldn't get on plane with 4 people on board without everyone up at the dash. Many years and many motor mods. Finally created enough hp to grenade a 2 bolt 302 so I built a bulletproof BOSS 302 producing over 500 hp. You name it that engine had it. Fuel injected 11 1/2 to 1 comp. FULLY BLUE PRINTED. After market heads worked over. Custom built through transom headers. Removed 200lb (flotation foam) installed full lenght stringers and new floor. Replaced wood on transom and raised X dimension 2 1/2 inches. Then installed ALPHA SS DRIVE that is 2 1/2 inches shorter than stock. This puts the prop shaft 3 inches below the bottom of the boat. The boat ran absolutly flat at speed - it needed almost no trim. At top speed the wake was only about 16 inches wide right behind the boat. Also took the hook out of the bottom and blueprinted the bottom while I was at it. The last straw was the new set of headers with 2 inch primarys and 4 inch collectors against the header builders suggestion. WOW what a change. Blew the alpha ss drive two weekends in a row. Bought 25 checkmate 251 And the story continues.

what about spinning a AA at 5400? How many ponys

quig
01-12-2002, 08:32 AM
Hot2boat... I think you misunderstood my post ... what I was asking was, when ,I get this motor together I am estimating 425-460 hp if I have to turn it 5400 rpm will that be too much for the A ?... however I am not even sure the motor will turn 5400 right now as it is still in parts & I have no previous experiences with a ford engine & the boat has not been in the water for 5 years so I was looking for some educated guesses as to what I will get & how hard the engine will turn & if the A is still the right choice??
p.s. expensive story Tinker http://free.***boat.net/ubb/biggrin.gif I think I am walking in those shoes right now http://free.***boat.net/ubb/smile.gif quig. I

Quig...
Loose impeller story..My boat was another one of those "lake ready" boats that has ultimately needed everything replaced and re-engineered. I had miserable flat performance when I got the boat. Lots of RPM and little speed. Upon rebuilding the jet pump, the wear ring was long gone and a rock had wedged itself in the bowl and machined a huge groove in the impeller (as if on a lathe). One more run would have cut in half like slices of bologna and trashed everything. Ha. I can laugh now. Wasn't funny then.

Quiq As you know I have a 76 CVX 20' 460 with aprox 425-450HP I put in an "A" ipmeller and wear ring from Aggressor ( I'm not cheerleading here thats just who I chose)and it keeps my RPM at about 5100-5200 RPM.

Thanks Jesse... if all of my calculations are correct then I should be right in that range too... providing the pump is not a piece of crap!!. Does the Ford motor handle that type of rpm willingly?? & I'm not be sarcastic here I really have no experience with how much or how hard the Ford can be turned.Does the stock balancer work up to those rpm's at a sustained rate or should I look aftermarket??.Does the Ford motor need oil restrictors up top how is the oiling in gereral?? I have just ordered the Canton jet boat oilpan approx. $800.00 cdn http://free.***boat.net/ubb/frown.gif but I don't want to take any chances . anybody have any input???

Can anyone tell me what to do to get a performance cam to work? Push rods, springs, keepers (locks), rockers, guide plates, studs? I bought some roller rockers which are extruded from 6061 T6 Aluminum. From what I have found so far I still need about $500-$600 worth of the above parts to make any larger than .500" lift work. I am planning on CompCams Extreme Marine 278 or 280. Then a couple of hundred more for valve covers. I have read that the keepers and springs are extremely important to keep from dropping a valve. They also cost more than I paid for the engine.
I have a 1979 CVX 20 with a 1970 Lincoln 460 with D0VE-C heads (10.5-1) and "A" impeller in the 12JE pump that I am rebuilding.
I am looking for a diverter.
I will get a "straight up timing set". Does it need the bearing and lock plate set that I have seen advertised?
What about oil pressure drop over 3700 rpm? The pan is front sump with the Ford factory baffle. This was with the old 1979 block and heads. Bearings look good so far. I did read oil pressure with a mechanical gauge off of the rear oil pressure port. I wonder if the remote oil filter (new filter) could cause this problem.
Does anyone make a chrome valve cover that fits over the roller rockers?
Thanks for any ideas you have.

Why wont the rockers work? Do you heads have the rocker studs with the stops on them? if so replace those. Clay smith makes nice rocker studs, if the stock rockers have a rail on them that goes over the valve stem then you will need guide plates, depending on the rocker you choose you may need to cut the pedistal for the rocker stud down the thickness of the guide plate.
The oil issue, buy some smith bros restricted push rods so you dont pump the valve covers full. I have crower rockers under mickey thomson valve covers.
If you are putting a cam in then you will need the right springs, so yeah buy retainers and keepers at the same time.
And if you are going to do anything with your pump call Jack at MPD.
