Boss cranksnout conversion

Hello everyone.
With the Boss conversion, does it still use the same front crankseal and spacer as the standard 460 crank?
Thanks.

seal yes
Spacer no.
My setup uses a Scat forging that was cut down by Adney Brown. The damper is the special one made by ATI for that application. My spacer ended up being .400" thick. Keith Fulp made the spacer for me. Yours may vary due to crank, damper, etc.

The snout dia. is the same..... it's just a case of the length being shorter @ ~ 3.500". Depending on who did the crankshaft, the key ways may vary.

Thanks fellas

the late model stuff does they use a standard crank, some with custom cranks[like mine] run a short shaft like a bbc,
