Nick,
This is my last automatic hot rod some 25 years ago. With DOT legal tires it would break traction with that dreaded 3rd gear to 1st gear downshift, and if in a street race I would lose because of that. Engine was a Ford 427 side oiler with 8 to 1 pistons that would allow 10 psi boost on pump gas. Only a fraction of the boost you probably run, seeing that big intercooler in your Supra's grille. C6 auto.

Sorry for the thread drift. When your '32 is running with your new 427, I'll shut up and listen.
