This is a McLeod conversion flywheel to run a Gen1 small block with a LT1 style T-56.
McLeod part number 460370. I paid around $460 for this from Summit.
You must use a clutch for an LT1 Camaro.
It is for an internally balanced 2 piece real seal motor. Everything except 400SB.
McLeod does offer a Counterbalance kit to bolt onto this flywheel to use it behind a 400SB for around $40.00
This has about 3000 miles on it.
I switched to a 1 piece real seal motor is the only reason for selling.
See my craigslist ad for pics.
