The block is here. This is what I decided. Y'all can tell me if I am off base somewhere, I am certainly no expert. I wish there was a builder here or near by.

360 block .030 over to fit the pistons available (though I may be able to get stock bore sizes now).

SCAT Crank
Diamond Racing forged pistons (641g with pin) 10.5:1 CR (iron heads)
Speed Pro narrow, plasma-moly piston rings (file fit)
Federal Mogul main and rod bearings
Forged, I-beam, 5140 chrome moly steel connecting rods with ARP Wave-Loc rod bolts (+$180 for H beam)
Crank assembly is dynamically, internal balanced

Weber aluminum flywheel and clutch ass'y
BJH Dynamics 7# vibration damper.

Iron heads machined and ported to match CR and cam specs.

Custom ground Hughes (Engle) cam. Ground to make use of the larger lifter bore on Mopar engines (Better ramp speeds)

2.02/1.625 valves

Air-Gap intake.

Unsure on Carb. Holley, BG, EB Thunder series. 750/800cfm. I am told a dual plane needs more than a single plane because the rating is at 1.5 inches.

With a 750cfm EB carb a similar engine was 485hp and 530ft/lbs and I don't have to spin it more than 6500rpm.

To my untrained brain this looks like a nice streetable motor that will take the strain of some road racing.
