I contacted Tom Lowe, as well. Man that guy is a wealth of information and a nice guy to talk with to boot!.

My build is starting aith a late 70's 292 short block, decked .015" Using a head from a 1967 250 cid with one of Tom's cylinder head kits(1.84/1.6" valves,locks, springs, etc) Also installing a lump kit.(seemed like some easy HP for less than $100)Milled .020"
Pistoms will be .040" over flat tops for a 307 cid with 2 valve reliefs, on 6" rods. Compression should be in the 9.3-9.5:1 range.
Using a 1990 700R4 trans with a Alabama Converter Co.mild stall.
Rear gears are 3.08:1.
Hoping the OEM torque of the 292, with a little mid-range turbo help will make this a smooth combo for a 4000 lb Suburban

Will be updating my build thread soon with pics from the machine shop and the recent body work.
