Hi Guys!

Imperially challenged here 1 thou ie 0.001 of an inch

So stock slant bore is 3.401 3thou oversize would yield 3.404?

BTW what is the max a slant can be bored oversize? that pistons are available for?

You have your math correct.

I believe Chrysler said the largest a slant could be overbored was 40 thousandths, or 3.440 total. That being said, there have been several known successful race motores bored to 3.5.

Stock bore is 3.400. Common oversizes are 0.010" (3.41"), 0.030" (3.43"), 0.040" (3.44", same bore as Chrysler's 2.2 and 2.5 litre 4-cylinder engines, opens piston availability options), 0.060" (3.46"). These, however, are not the only oversizes possible. By spending time in piston and ring catalogues, you can come up with almost whatever you want. Boring 0.10" over (3.50") makes a whole whackload of Chevrolet pistons available, but only particularly carefully cast engines can support such a large overbore; sonic checking is necessary.

(...and then there's the mysterious "906" block casting from Argentina, specifically made to support very large overbores...)

Too many people who were born on third base actually believe they've hit a triple.

Argentina is a mystery - special over bore blocks, those funky cast headers
