Ever race an older muscle car and spank 'em?

I have experienced the raw power of a good old big block V-8. The first motor I rebuilt was my dad's 427 low riser in his 63 1/2 Galaxie (at 11 yrs old).

This car pulls like mad, with a 3.00:1 gear. Mind you this is an original 390 car with a "cruise 'o matic". So in its place is the 427 with a C-6 (3500 stall, reverse manual valve body). I know that the converter is a little loose (especially with the gear), but we planned on changing the gear. We will put a 3.91 or a 4.10 with a posi or locker. We need to get the correct 31 spline axles to go into the rear.

I realize the potential too, but I just wanted to see if anyone ran across some cocky has been and spanked 'em.
