Hi!

Been a real long time since i posted, but the time has come to try to mate a cast iron powerglide to my gmc 270. (Yes, i know th700 etc are better, but who doesnt like a challenge?)

My question: what flexplate can i use? My crankshaft has 6 bolts.

I see that a chevy flexplate from the same vintage (1950’s) can’t be used since it has another boltpattern and the centerhole is to small.

Hamb forum told me that a pontiac v8 flexplate could work, but i tought you guys perhaps know for sure?

Thank you in advance,

Fred
