Have a Good One,

In this Post that I had made previously, I want to Clarify what I said.

While rereading My Posts last night I realized that this information may be a little misleading.

I PREFER to have a minimum of 0.125" of Wall Thickness on the "Non Thrust" (Front and Rear) Portions/Surfaces of the Cylinder Bore and a minimum of 0.185" on the "Piston Skirt Loaded" (Inner and Outer) Portions/Surfaces (Not just the Thrust Surface) of the Cylinder Bores as a MINIMUM.

That's what I PREFER. BUT, what I have found over the years is that I have had a lot of trouble finding Blocks that could be Overbored more than 0.030" with that much Wall Thickness Remaining. So, because of that, I've had to adjust what I would accept as a "BARE MINIMUM". That's where the previous specs. of 0.100" and 0.150" came from.

I hope that makes more sense,
Larry S.
