just pulled down the spare Chev 350 engine as it has been tight to turn over, even with a power bar and pipe it is tightish. Pulled the heads off and found Piston size is .060" over, Bores measure 4.050" (Standard Chev bore is 4.000") so that is .010" difference, so it appears the slugs and rings are slightly too big, Crikey, Amazing what you find when you check Shoddy Engine builders work

actuallycosworth designed there latestF 1piston so the top of the piston grows enough to deform against the bore wall which adds to the compression seal, hi UNCLEJAKEyes a lot of high tech/ performance engines are pre heated and oil pressurizedB4 start up to get the correct running clearances.

Saves wear on the rockers if the lobes are worn down.

should post photo's to show what an absolute mess this engine is in, waste of a 4 bolt block really due to being not looked after.
