"I think I better keep it to non forced induction."

O.K., then it's going to have to be some good heads, 11.0:1 minimum c.r. and a long non-hydraulic cam. You'll have to run a tight squish to facilitate pump gas.

My recipe for such a beast might go something like this.....

Magnaflux and bore the block 0.030" to 4.030", cut for zero deck
Magnaflux crank, grind to next undersize if non-concentric, micro-polish
Eagle rods, I-beam, bushed for full float (H-beam preferred, but expensive)
SRP forged pistons, pop-up, part #147752, 11.4:1 c.r. with 68 cc heads
7 qt. oil pan, high volume pump, windage tray, crank scraper
Air Flow Research 195 heads, 68 cc combustion chambers, chambers altered by AFR to accept SRP piston pop-ups.
Edelbrock Performer RPM Air Gap intake. There are those who would argue that a Torker II would be a better choice and they may be right. The increased volume that each cylinder would see would help to cushion out the reversion that you will experience with a cam of this size. A Victor Jr. would be too large for this motor in my opinion.
Holley 0-4779 750 cfm carb.
Fel-Pro 1003 head gaskets, 0.040" squish with zero deck
Fel-Pro 1205 intake gaskets
Fel-Pro 1404 exhaust gaskets
Isky Z35 solid lifter flat tappet cam, duration 288 @ advertised, 254 @ 0.050" tappet lift, 0.525" valve lift, ground on 108 degree lobe centers. Will rev to 7,500 with Isky engineered kit (highly recommended).
Roller rockers
1 3/4" equal length headers into 3" collector, reduced to 2 1/2" pipes to the back. Mufflers of your choice.
Cold outside air to carb. DO NOT UNDER ANY CIRCUMSTANCES ALLOW THIS MOTOR TO BREATHE UNDERHOOD AIR.
HEI distributor recurved by Performance Distributors, Memphis Tennessee. 12 degrees initial, 24 degrees mechanical advance.
T5 5-spd rebuilt by G-Force for 600 ft.lbs. torque, 4.10 to 4.88 rear gears
Pedal to the metal and side-step the clutch, shift at 7,200

Are ya grinnin' yet?
