Does anyone know if there's a difference between the flywheel register (centering hole) between the early 273 (64-66, 122 tooth) flywheels & later V8s that have 130 & 143 teeth? Maybe someone had both & can do a quick measurement?
Things I know: early slant 6 & v8 had different size (6 was smaller). Later V8s (big-small blocks) all seemed to have the same 6 bolt pattern & register size. I put a 65 v8 122-tooth flywheel on a 68 318 crank & it fit (gave both away). Automatic cars do differ in converter centering hole sizes but this is a different animal.
