360 Engine Rebuild kit.

Sounds like the pistons are going to be low compression stock replacements and a Clevite 77 cam will also likely be a stock replacement.

If you want to keep the low compression of a stock 70's 360 then that kit is a resonable. The parts are all good quality.

I picked up a kit from Mancini Racing that did not include the cam or timing set but did include ductile iron moly rings (the cast iron in the kit you are looking at wear pretty fast and will wear the bore too) and had Keith Black 107 pistons for $401.00. This kit is the way to go if you are looking to build some decent power.
