Keith, you're dead on...
RAI Auto = 92
RA1 Manual = 321
RAII Auto = 12
RAII Manual = 98
This includes all body styles. The RAII Firebirds are arguably some of the fastest 1/4 mile cars Pontiac ever built.
Keith, I sent you a PM with my email addy...If possible, I would like to see those pics!!
Andy, a numbers matching 400 4sp is a great find in itself...let us know how you make out.
Thanks,
Mike
