Crankshaft Difference?

[MichBC3]

Are there any differences between a 1989 Turbo Trans Am crankshaft and a 1986-1987 Buick Grand National crankshaft?

Thanks, Bob

TTA crank is cross drilled for extra oiling.HTH

Mucho thanks for the info TT/AmeASAP. Don't know where else I might find it otherwise. Your car pic looks great!

Why? Its not any stronger than a GN crank. As a matter of fact, they both have the same casting numbers.

Good luck finding any Buick crank.. cross drilled or not
