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

Re: Rear gear change
Joe
If you can cruise @ those RPM'S you will will be OK I think. My L78 Camaro, M22 with 4.10's and F70 14 tires is at 3800 R's at 62 MPH. Now I sure would not take off on a power tour, but I sure as heck ain't given up those 4.10's  You need to do this  at times  I do make some 20 to 40 mile trips on the I state's and 60 seems to be my comfort zone. Good luck. Mike
