After giving it some serious thought I am going with a solid lifter flat tappet cam. My cruising rpm is about 2800 with the gears and tire size I have. I'm looking for a LOT of low end torque. Bear in mind it's rare to "cruise" in Hawaii at 55 or 60 for very long. And even more rare to exceed 60 or so except for VERY short distances. So cruise rpm is the biggest issue (1st gear, Waikiki, all them tourists covered with oil).

Our road race track is SHORT and twisty. I have fairly high trans gearing and 3:31 rear gear. 1st gear is good to 65 mph. I GOT to have serious bottom end to come off those corners with that gearing. I'm thinking "short oval track" application for the cam.

The drag race thing was "cool", but I'm over that. I'm a road racer not a dragster. Can't see where the extra money (a LOT more) for hyd rollers would be a good cost/benefit analysis for THIS build. I'm thinking 2500 to 6000 rpm range with a "red line" of 6500 or 7000 at the top end.

Chris at Shelby American in L.A. will be fabricating custom pistons. Shooting for 10 to 11 C.R.

Think "cam kit", like Geroge at Gessford sales. Cam, springs, timing chain and gear, keepers, shims, etc. The whole ball of wax matching components.

Federal Mogul rod bearings for my 428SCJ rods (.020). What else am I missing?
