Inliners International Forums General Discussion Engines New to inlines, critic my build plan!

I show compression height of the 250 piston at 1.655, same as the 307 piston. So that would put your deck at .030"

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

Either way, if your deck is .175" something is wrong, that would jive with using a 230 crank and 307 or 250 pistons. Should be easy enough to measure the stroke and find out!
