The Stovebolt Site Forums The Shop Area The HiPo Shop 5.3L V8 flywheel question

What flywheel application can I look to, to purchase and bolt to my 5.3L LM7? Seems they are all backed up by automatics. Can the 4.8L or 6.0L flywheels work? There are many manual applications for the engines.

cavebull,

I'm pretty sure ANY 1987 or later Chevy/GM V-8 flywheel made for the one piece rear seal will work! Try 'Vette or 1 ton work trucks.
Clutch will be the same form the '60s on.

Best wishes,

Les

Thanks Les,
Curious what I will be getting into if I go this route. I know the blocks are different but the bellhousings (assume)are the still the same. Always looking as possibles before I go gettin' dirty hands and bloody knuckles, and thats just pulling out the wallet!

Do you know the LS1Tech.com forum? It specializes in the LS family of engines and there is huge knowledge available. I know of at least 2 different flywheels for these engines, but that is all I know!

Cool, I will give'em a look right now.

From Jefferson Bryant's book, you can match an LS-based motor to an older transmission. Get the GM retrofit bellhousing which allows the LS motors to be bolted to Muncie, T-10, Saginaw, Richmond, TKO, Tremec T56-011. See Pace Performance who is a reseller. LS truck flywheel is used which is GM partno 12561680 12-inch clutch and pressue plate P/N RAM88744 and 6 pressure plate bolts P/N 12561465.

He also says McLeod and Advance Adapters offer aftermarket versions of the same thing.

Hope this helps.

R-BO,

Thanks,
