[QUOTE="Johny25, post: 284708, member: 7791"] What year 25 do you have? Anything over .002 should be bored to .030 over and oversized pistons installed..... that is assuming we are talking about the 77' and later 3" bore 31.8 ci blocks My guess is when you get in there you may find the taper out of spec or the roundness of the walls may be out also. I would bore it out myself if I were thinking on doing a complete rebuild. [/QUOTE]
