455 & 425 flex plate
Anybody happen to know if a buick 455 flex plate will line up with an oldsmobile 425?
I'm trying to install a TH400 and I'm having trouble finding a flex plate that will work. The flexplate out of my old motor does not line up

No it will not.
Try installing a TH350 converter using the 425 flexplate.The crank pattern is different on 425s(see tech section). Most stock flexplate only have one converter bolt pattern on them. Using a TH350 converter w/stock flex should mate the two.
May need more clarifying as to what doesn't line up.
Other option: ATI flexplate #915563.

You'll need a flex plate from either a 330, 425 or the 1965-67 400 engines to fit the bolt pattern on your crankshaft. I may have a used one and suspect others here would too. I'd encourage you to create a thread in the Parts Wanted section. John

i totally understand, I somehow fit two GM B bodies in my 2 car garage for winter storage, they look like a pair of sardines in a can, but this has left my garage useless until spring
