i dont kno what u mean by 331 cleveland, unless ur from australia. but if u mean 331 clevor thats a diff story and it will be a bit more to do. but a .60 over bore is a lot for a little 302.

unless u meant a 351 cleveland? probably. and if u got some money and a good skill wit motors the cleveland will run cirlces around just about any small block. the heads on that thing are huge and flow so well. i would go cleve. but a 302 is always a good motor. 60 overbore might bea little much. u will be happy wit a 30 overbore, and then put boost to it.

I agree that you shouldn't bore a stock 302 block more than .030 over....You start running into overheating issues.....
