Yes, but they have to be done correctly. No shortcuts—two buckets, microfiber sponge, etc

@Frankenchevy

What are you using for a throw-out bearing? Another subject that seems over complicated in these mismatch of part conversions.

350 motors are neutral balance flywheels/flexplates and are internal balance motors... its the 400sb and the 454 that are external balance. and the extra tall foot 208 adapter is for flat crossmember before 83.. W crossmember 83-up use short foot adapter.

Weird, every 350 flywheel referenced in summit and RAs catalog says eternal balance...

I believe the flat CM went through 84. It’s what all CUCVs have and they’re all based on ‘84s

The '86 and later engines with 1-piece rear main seals use flexplates and flywheels with a counter weight.

The 'W' crossmember started in '85.

I haven’t shot marbles since cub scouts. I remember asking if there was an achievement patch involved and immediately losing interest after finding out there wasn’t.

I need the patches Perry!

I think your scout leader dropped the ball. Cub Scouts had a marble belt loop.
