i have a 1979 z28 camaro with a chevy 350 small block. i have a 650 holly carb on it and ever since i put it on it last summer if i get on the gas too much it shuts off real easy. we came to the conclusion that it was vapor locking but now its winter time and not too cold but cold enough it couldnt vapor lock.. and it still shut off. i think it has the original fuel pump so could it maybe be that the fuel pump cant keep up with the carb? any other explanations? what should i do and how. i need help so i can get my baby back on the road!
