Re: Anyone running a 3.25 ratio rear?
I have several friends running 276 engines L-100 cams in heavy cars. these cars have 3.78 rear gears. However, they also have a Michael OD unit. now this puts the final drive into the mid 2.5/ 2.8 and yet they can drive very comfortably around in hi range. so I don't think a 3.27 would bother a well built engine, and give great economy.
