I say go with a 454. if you want rumble and torque(great acceleration)


davidh......What do you think of as good mileage? 15mpg?

I've had a 305 and 350. the 350 is better on fuel. much better intake and exhaust system. plus more torque to move my est. 4600 pound truck.

the 350 even has 3.73 rear gears. with the 305 I had 3.08:1 rear gears.

I get 12-13mpg.

I'm wotkin towards building a 454 for my truck. with an electric fan and a cam for torque and mileage. I'm shooting for the same 12-13mpg on regular pump gas.
