chevy 250 L6 (.080 or .125 overbore)
I would like to see if someone can clear up this overbore situation.
I just picked up a 250 L6 out of a 66 Nova and a 292 short block for future build. I know that I can overbore this motor and install a set of .080 over pistons from Summit that have a smaller .085 dish. This setup would make about 9.8:1 CR with a -0- deck.
I am thinking of trying a .125 overbore and running a set of 327 sbc FT pitons as more of a hot rod motor that is going to make 1/4 mile passes only.
Problem is I can not figure how this combination works in a 250 block with out changing cranks to use a 194/230 (3.250 Stroke Crank) and even at that the C. H. is not right on the 327 piston.
Maybe I am just losing it!!!!!! What ever "it" is.
