it's going to depend on your pistons and how much clearence they need. If you were to buy a set of pistons mmade of 2618, they need more clearence then say TRW and you may need to hone it enuff to staighten them out. But if you are buying new pistons, then just bore it
if you measured that 90* to the pin ---even with the pin it's a tad loose for that piston. But here is the main point. The bottom of your bores are the original bore size, there is very little wear there. If you hone it till the bore is straight, you will be approx. 2 maybe 3 thou looser than new. You decide
Thanks for the replies. I appreciate all the knowledge here on these boards.
It sounds like you think things would be a tad loose. That's good information to have.
Part of me wants to put this one back together, and part of me wants to order a 540 short block!
...just weighing all the options.
Hey clutch. without knowing the piston diameter and cast or forged. off the top I would hone and buy .005 over rings and file to fit and be real careful on the beak-in! Your'e numbers are close enough to work and depending on the pocket book and what you want go with it. IMO M
