Good info but are the 168 & 139 tooth flywheels chevy or GMC & what year. I've been told that there is a difference. Also, was the '55-'57 starter used?

I've never run an inline engine in anything before so I'm just trying to get my ducks in a row before I jump in with both feet.

Honestly I have the 2ton clutch bellhousing etc. currently attached to the engine & a saginaw bolted up to it. I'm missing the 12v starter, but I want to know what I can upgrade to that might be alittle lighter weight with less rotating mass. I'm a low buck guy on a tight budget like most of us are, so I'm also looking for the most economical solution to my delema too.

Thanks,
