Re: Rear gear change
Engine has about 3k miles since rebuild with NOS W31 cam and higher than stock compression pistons (not flat top, but lower cc).
M20 was rebuilt last spring. I think I'm going with the 3.73's and worse case, I can travel country roads at 50 MPH if it's that bad on the freeway. Calculators say I'll be between 3100 & 3200 RPM @ 65 MPH with my tires. 3.42's would lower it by roughly 200 RPM. Appreciate all of the input! Joe
