Hi
I have a late model 302 windsor roller cam block in an early model car, the engine has huge vibrations at low engine revs up to about 2500 rpm and then disappears. it has a flywheel, twin plate clutch and toploader from an early model (pre roller block) car bolted to it. The engine has the correct harmonic balancer and only a single belt pulley mounted on balancer. Any ideas?

Early crank or late? they are weighted different balance wise, I'm assuming late block/crank with early flywheel/balancer = bad vibes

As blue66coupe said, you probably have a mix of 28oz and 50oz parts.

Yes,
have seen this before, you need the 50oz flywheel. You will need to remove your existing unit, to confirm the ring gear count and bolt spacing for the clutch, before you order

Most types seem to be available.
