Actually I have 1.675 for some 307 & 327 pistons, that would bring it even closer to .010" deck.


Just wondering who is going to bore to 4.0" & use 327 pistons?

Actually I have wondered about this -
Since the six and SBC are the same bore spacing, and the SBC comes at 4.000 bore and goes to 4.030 or even 4.040 if youre lucky, why cant the sixes in general take a 4.000 bore? Are the walls deliberately thinner? I guess so, I will have to recheck my drill-bit data but I know the space between cylinders on a 350sbc is pretty small.

Maybe if you did a sonic and lucked out, will any of the sixes take a 4.000 bore and still have .100 wall left?
