Without all the build specs. Just plugging in conservative numbers....Estimating:
HP at the Fly - 288 at 4500
HP at the Wheel - 245 at 4500
Torque at the Fly - 386 at 3500
Torque at the Wheel - 328 at 3500
65MPH Cruising RPM around 2600ish | 155 HP/325 FT LB
*Added a Ignition Curve chart for you also. Would play around with 15* INT |12* MECH w/ 2 Heavy Springs. And then tinker with Vacuum advance to give you Total Timing around the 48-52* range at cruising. **Adjust for Octane/Pinging
