I have a 72 Nova w/ 305 SB out of an 85 C-10 pickup. I am having problems with it bogging on acceleration very bad. The car comes as close as it can to stalling out totally. As I press the gas pedal while setting at a stop light, the car will ramp sharply and the dive even more sharply and has zero power. I pump the gas and the RPM's don’t change. If I let off the pedal totally the engine will ramp back up but if I press the pedal at all it dives again. It takes 2 to 300 yards to gain any kind of momentum. I tried dropping the car into neutral while it was bogged and the engine RPM's spike but when I drop it back in to gear it dives right back down. I have replaced most everything on the car so I don’t know where to go from here. This is my daily driver so it is hard to pull out into traffic when I can only go 10mph forever. It makes it no fun to drive when you can't get on it and show off, its more embarrassing that I hold up traffic.
