Well, its a stock replacement piston for a 67-70, 250-300 hp chevy 350. Comp ratio is not stated.

Your piston is a forged aluminum, .030 over stock diameter.

The following numbers are stock equivalent (sp?) for the above engine.

2244P SEALED POWER, L2256F TRW, L3022F TRW , P557 BADGER
350 VENOLIA, 345NP FEDERAL MOGUL, 350 LUNATI, JE 139904, 99579 ROSS, C6-CP CP

got the info here.

Piston Code Dicephering

9.18 Malibu

I Have A 1986 Trw Catolog. It States The Pistons Are For 67 -70
350 Cid. H.p. Ratings Are 250,255,295,300.
These Are Cast Not Forged, All Forged Pistons Start With L2000f, And Cast Start With L3ooof. No Data On Comp. Ratio.
I Would Say From The Year And H.p. Ratings Probably 10:1 With 64cc Heads. Hope That Helps,
