Trw Bbc 454 Forged Pistons Part # L2307af .060 Ls7 468 Speed Pro Sealed Power on 2040-parts.com

Up for bid is a Set of 8, USED TRW Forged Pistons, Part # L2307AF 030. They are high compression domed, with 4.310" Bore, 6.135" Rod length, 4.000" Stroke. 1/16", 1/16", 3/16" Ring Grooves. They are for Chevy 454 Engines with Open Chamber Cylinder Heads. This is often called the LS7 piston as this design was first used for the 1970 and later GM LS7 engine package.   Stock rated at 12.5:1 with 118cc chambers.    Easily achieve over 13:1 with slight milling of the heads.   Deep valve reliefs accommodate most cams including many solid roller grinds without further flycutting.   This set was in an engine with .722" valve lift with no clearance issues.   Floating wrist pin style with Spiro Locs.  The wristpins are oversized in this set and are a big block Ford size of 1.040" diameter instead of the normal BBC size of .990".   This was done to correct a worn bushing issue with a set of connecting rods so they could still be used.   It also gives a stronger / larger piston pin.   Some of the skirts are scuffed as pictured and the opening bid reflects this.   These were over $60 each new.   All the pistons are crack free and the engine did not suffer a failure.   It was upgraded to a stroker rotating assembly for 496".
