All Chevy small-block and big-block engines with one-piece crankshaft seal require an externally balanced flywheel or flexplate. Find the right part to match your engine.
Year of engine: 1979-90
Outside diameter: 12.75"
Crank flange bolt pattern: 3.58"
Clutch diameter: 10.4
Starter ring gear teeth: 153
Technical notes: Lightweight nodular iron. Counterweighted for externally balanced 454 engines. Use with balancer P/N 3963530.
I believe that would be the correct flywheel.

mark,,all big block flywheels 1 and 2 piece seals are the same bolt pattern..
john have your brother use a bravo inner plate,,you will have 2 extra holes in it..this way you could use the bigger flywheel..if he use;s the smaller flywheel thet are harder to turn the engine over and hew will also have to change the starter..

then there is always the half-a$$ option of the little add-on balance plate to a neutral-balanced wheel. i didn't now anybody made a 454 small wheel...you wwill need a serious starter. buick 455. rebuilders number is 3567. or take 3664 low-torque chebby starter and put hi-torque armature and field housing in it.
