Overbore...what is too much? (not 2130cc) 140-160

posted by  someone claiming to be kingcong on  Sat Oct 18 03:19 CST 2003 [RELATED]

I know this topic has been disussed before, but my question is a little more specific than how big a piston can I put in the b20. The pistons I removed from my project engine are marked .030" which is .030 over stock. This has been mentioned as the max overbore for a pre 74 b20, but I've noticed Ipd sells mahle .040" pistons. Is this too great an overbore? will I run into problems with such a minute difference?
