Re: 5.7 Vortec for 72 C20

Do you have the bellhousing mounted starter or block mounted? The original SM465 would have 168 tooth flywheel with bellhousing mounted starter.

I'd by the MSD Streetfire HEI since it comes with the melonized gear. I think the GM performance parts one does as well, but I like the bushings and spring assortment for tuning that comes with the MSD.
