Inliners International Forums General Discussion Hi Performance 250 Zero deck question

It sounds like those pistons he has sit down too low in the block,if they are copies of 307 pistons.

IIRC, the TRW forged flat top pistons I have,I only had to deck the block about.010 & now it has a positive deck from.001 -.004

Or the block has a little taller deck?

I would just deck it .040 if it is not an all out race engine,it should be fine.

Or buy pistons that sit @ the proper height.
