Do you have the cam card? It should tell ya there. If you don't have it, you should be able to find specs on the mfg. website by part number. I know Comp lists their specs online. The one in my friend's BBC pullling truck is a Comp mech. roller at just under .800 lift- it specs .018 cold on both int/ exh.

Timing... lots of info needed to call that

sorry i can't help you with your question but this motor sounds like a monster. Wats the estimated power from it.
