Slightly different question than the one in the Q&A section.

Anyone here ever drag raced a big block with a 4-speed and 2.76 rear gears? How fast did it go?

And whats the fastest anyone has heard this combo go on the strip? I'm sure over the decades people have done this for whatever (odd) reason, there must be some stories.

Basically, i need a 5 or 6-speed for my car. I can wait 1-2 years to get one, or i can drive this rig this year with the above combo. Mine will be in a 70 Challenger, 383 or 400 stock stroke lowdeck, 400-450HP (big cam, higher RPM build), 2.76 gears, 3450-3500 vehicle weight with me in it. Its a road race driver, but will see very occasional drags.
