flywheel identification

will those flywheels work on big blocks also ????
Well, not a 11 inch flywheel that is balanced for a 360. OP wrote that his had three 1 1/8 dimples drilled in it. But a neutral balance 11 inch unit from say a 318 should be the same as a B or RB 143 tooth 11 inch flywheel. A neutral balance 10.5 inch 130 tooth flywheel is the same small block or big block*, so why wouldn't a neutral balance 11 inch flywheel be universal also. * six bolt flange, 8 bolt flange big block cranks- all bets are off.
