RB block 4.350 bore
4.250 crank with 2.200 pins
6.800 Chevy rods
12.5 CR. (Diamond flat top shelf piston at zero deck)
Indy EZ heads with CNC porting by Modern Cylinder Head
Indy 440-3 intake or 440-2 with 4500 adapter
1050 Dominator carb
Flat tappet cam about the size of a MP .620
2 inch headers

Torque peak should be around 5200 rpm with power peak around 6200 rpm.




i'd use a dome piston for around 14:1cr, and std EZ-1's with some minor clean up/valve job corrected, and more than likely a roller cam.
the cost of the roller set-up or the CNC porting is about a wash....and i'd rather just invest in the roller cam right off the bat, then have the heads ported later on down the road.

with a roller and 14:1cr, it would make over 700hp with ease.
