lack of horses
I have a 74 chevy 1/2 ton w/350 4bolt. This is the original motor, when Igot the truck the cam was completly rounded. I have changed the cam,intake manifold,carb,&dist.This motor came with a 2bbl and this what was replced with. When you go to take off the motor tries to cut out but if u feather the gas pedal it comes back around but with serious lack of power. I know this motor is strong a friend has same setup and running fine. PLEASE HELP!!
