it runs really good. better than we suspected after rebuilding it. i don't know if you all will beleive this but i have gotten it up to 120mph. thats good from what i have heard. the motor that was in it before was a 350 and it was torn up inside. the intake manifold had a crack so the old owner did not fix it and it screwed it up. so one of these days i will rebuild that one too. but why do you say "techinspector1 DO NOT, I repeat DO NOT spend over $50 on this lump. The 305 was Chevy's redheaded stepchild. If you want more horsepower, sell the car and buy something with a 350 in it."?whats wrong with em?
