Original 454 LS6 Engine Complete Intake to Pan

[SuperNovaSS]

This is a complete LS6 454/450 engine from carb to pan minus the cam and lifters. It was removed from a 1971 jet boat so the date codes are all late 70-early 71. This would make a great replacement engine for an LS6 Chevelle or other hi perf warranty engine.

The numbers on the engine are as follows:

Block casting number: 3963512 Factory 4 Bolt Main

Head Casting: 3964291 Factory Rectangular Port Hi Performance

Crank Forging Number: 7416 Factory Steel Crank, Nitrited and Cross Drilled

Piston: L2349 .030, TRW Forged Piston, 1970 LS6 Replacement

Rods: Hi Performance Chevrolet "Dimple" rods with factory 7/16" rod bolts

Intake: 3963569, Factory High Performance Aluminum Intake


This is an original LS6, not a cobbled together bunch of parts. The engine is complete from intake to pan minus the cam and lifters.

The block has been bored .030 over and has almost no use since then. The tops of the cylinders have ZERO ridge. There are no breaks, sleeves, or other repairs/damage.

The heads look great with no porting or modifications. The valves sit very high in all the seats. Even the original high lift "L" rockers are still intact.
