502 EFI rebuild project

[Beer-30]

Just looked at the website and the PowerTips that you have are for 450 HP and down. Bullets are for 450 HP and up.
I'm not trying to take the wind out of your sails, I just don't want to see you put all this effort and money into a nice motor and be dissapointed by cutting exhaust flow by a 1/3.

Beer-30 - That is something that I didn't realize. I originally purchased the bullet clamp-ons but when I got them, I decided to return them and go with the bolt-on style. When I went down to exchange them they were out of them but had these. I compared the two....length, inside/outside diameter, etc., but the only diffence I saw was the outside diameter. I wonder how much difference there could be in just that dimension? I am sure the bullets will flow better with the bigger diameter, but is it enough to make a diffence on a motor that will only be in the 500-525 HP range?? I am not sure how much of my boating time will be spent at the WOT range and will I miss a mph or two....probably not. Besides, there were almost half the price of the bullets. I will definately keep in mind though. Thanks for looking out for me.

It'll make plenty of difference. I'm dead serious about this, I am not pulling your leg. Gibson did extensive testing on these units and these won't work well for the HP you will be pushing.
We all know that we don't figure on running WOT much, but it sure seems to happen alot.

Looking real good Kevin. I think you have inspired me to rebuild mine. I have been looking at Tyler's modification for some time now just never stepped up and tried it. Did you ask Tyler about doing any modifications to your intake? Shortening runners or extrude hone to open them up a bit for more flow.

No port work on the heads? Isn't that part of the Crockett recipie

I didn't talk to him about any of that, but I am sure it would just add more hp and of course more $$$ to the project.

His recipe (+100 hp) just uses everything as stock except the larger valves. I could have had some port work done if I wanted but the pocket book is running low....maybe on the next rebuild.
