Sonic checking my 71 360 block

Thanks for the info. I was checking the passenger side bank and fou.d a spot that was .177 but of I moved it a 1/32" it would read .220 move the other last that .177 and it would read .220 again being moved a 1/32". Sounds like I have a pretty descent block to start with. Sounds like Shady dell was good on anything over .125

That’s what you will find when you start sonic checking as many blocks as you can. There is literally zero consistency because they are castings.

I wouldn’t be afraid to take that think to 4.100.
