Runs great, but since I switched to HEI the car's revving 500 RPM's too high.
With the points I was doing 2600 to 2700 at 65, now I'm at 3000 at 55  |
Changing to an HEI will not change the RPM/miles per hour formula. That is purely a function of gear/tire combo (and transmission or clutch slippage, as applicable). Perhaps your tach needs calibrating?
