You could try Wilcap. They made my Lotus flywheel. I expect to check with them for the Dodge when I get that far along. How far from a GMC is a buick bolt patteren for the bellhousing to block? There is a steel GMC/Chevy to late Chevy blowshield adapter on EBay that a local salt racer is selling.
Thanks Mike , I'm on it !
Rich , here I thought you were SLAVING AWAY ! ... on second thought ... what am I doing in here .
I left a message with Wilcap . I bet it will work out .
I hear tell of a 427 Ford wheel working with a little machineing . I'm hoping for "quick" ideas / suppliers . Hopefully Wilcap has specks and can jump on it .
I have a couple Chevy blow proofs , but the stock Buick , thick cast bell is easily converted to the T-10 pattern and flange . It's at the machinist.
