Alright folks, I got this thing running like a top. unfortunetly I dont own the carb that im using but I do know that a dif carb will work wonders. I dont know what the big difrence is but a friend of mine is letting me use his holley 850 single feed dual bowl spread bore carb. he said it came off his olds cuttless 455. An this thing shits n gitts. it sucks its winter here in maine but this thing is balls to the walls. I cant even imagine what this would be like with a set of the aluminum heads makin another 100 hp. this thing is crazy. I am so happy i cant even express it. thank you to everyone on here for there ideas. they were all 100 % helpfull. No more flat dead spot. an its weird but it doesnt seem like its dumping as much fuel as the 750 was. It is a totally difrent car. I just need to find my own carb now LOL. so thank you all very much.
