Building 526 Hemi for fed. Lots of used top alcohol parts. Pistons are good for 12.5 to maybe 13.25 depending on gaskets and rods used. Would like 14 to one and wondering waht say the 1.5 to one would be worth in power.
4.31 bore

My thoughts are it might pick me up 25 hp to 30 and that not a lot for cost especailly in bracket race engine.
