N/A & Turbo crank

[TomG]

How can I tell a N/A crankshaft from a turbo crankshaft by looking at them? Is there a part number I should look for? Anyone have any pics?

Thanks,

Tom

Turbo crank has rolled fittets on both main and rod journals. N/A cranks are only rolled on the mains.

Thanks for the reply, but what's a Fittet?
