Is the car Carb or TBI or TPI? Either way, if you are pulling the motor, replace it with a 350. Rebuilding a 305 is a lot of work and money for not much end result.

can't agree more.

don't be afraid of compression ratio, I'm at 10.5:1 and run pump gas all day, just make sure its 91/93 octane and you'll be fine

trust us when we tell you, spend the extra money for the 350, the performance gain is warranted

You can use any 350 non-vortec motor.

If U want to keep the TPI U would have to get larger injectors and a chip.

If U want it to be fast U would rip the TPI off and go with a carb.
