Need a new carb

I suggest you call Jessie at Bigs Performance and tell him your problem. He will know if your carb can be repaired, and would set it up perfectly for you while he had it. I sent my Holley to him for rebuild and they did a great job on it.

if you liked the edelbrock, stick with it. im betting you took it out the box (originally) and ran it with no problems. the two i have used needed no jetting changes or anything. since the motor liked it before, it will like the new one. now, if you want to go holley i would suggest a 750 vacume secondary (i know, everyone wants a double pumper). on my olds 455 i did swap over to the holley. bought one from the recycler (free ads) for $75 and it looked brand new. i bolted it on and it didnt need a darn thing. i dont think i even needed to adjust the idle. yes i got lucky, but with those carbs they come pretty close to what your application is. the double pumper MAY give you a bit more acceloration, but i doubt it. not with a stock 455. obviously these are just my opinions and others will vary. currantly i am building a 454 BBC with 7.5-1 compression, peanut heads (gen6) and small cam (GM 2296 factory roller), performer intake and i will be bolting an edelbrock 600 on it. yep a 600cfm. it wont see 5000 rpm and doesnt need that big of a carb, plus it will get the 20' kachina jet killer fuel economy. over carbing is all too common. IMHO. good luck and keep us posted.
