20+ years of "Building 904/727 for drag racing use"

I just read on another forum that a SS guy (I think he’s a Ford guy) says he’s using a Proflite in his car.

there‘s 904 guts in GM 200 cases as well as Ford cases out there.

my friends 383 stock eliminator wagon is a tenth and a half quicker with the 904 aluminum component pro flight over a 727 he tried.
