it would be the same for all v8... unless you want spacing and bolt size. i usually do the star method of installing the flywheel, if that is what you entend.

Bolt size I have, bolt circle and any different spacing a particular bolt might have? Is one bolts spaced different so the flywheels can only go on at one position?
Thanks Tony |

6 on 3.750". Indexing bolt is rotated clockwise 5 degrees. Viewing from transmission side. Same as a Pontiac V8.

Same bolt pattern, Pontiac used a 2.750 center hub on the crank, AMC used a 2.687".(later models earlier cranks centered the flywheel off the O.D. of the flange.)

I noticed Buick center hole looked the same as the ones on the Nailhead TH400 adapted AMC motors but never checked the bolt pattern.
