Re: what's wrong with 305's

I gave my last 305 away when the 383 went in. Compression was so low you could hand spin it with the plugs in....so yes you could have had mine!

Re: what's wrong with 305's

You can build the ding-dong out of a 305 but it will cost a bit more than it will to get similar results from a 350.

I had a 95 short-fleet with a vortec 305 and, though it was no Corvette, it was not disappointing in the least.

Re: what's wrong with 305's

If I am not mistaken the 305 cannot be bored much larger than what they did at the factory so guys who want some get up and go use a 350. In 1985 my friend had one of the first IROC z28s and that car scared the crap out of me, then after he let me out he would burn posi marks a good 75 to 100 feet. Nothing wrong with the 305.
