Build thread- 73 duster, forged 5.7 w/ PS and AC, 5 spd, big brakes and floater rear
The .64 OD in the car is really just a cruise gear. It's a 2500 rpm drop (6500 down to 4000). The .82 is much better- 6500 to ~5300.
Also- I'll probably swap rear gears at some point.
The biggest issue is the track I've been running is shutting down for good in June. So there's no good reason to 'gear' the tranny and rear for that track- I probably won't get to run it again.
Big bend open road race is the end of this month. I'll be running the 135 mph average with 168 mph tech. I would prefer to swap the OD and rear gear by then, but I don't have time. So we'll be accelerating from 4,000 on up trying to get to 168 to help make that 135 mph average! The ideal would be a .82 with a 3.00 or 3.25 gear. It would allow a strong gear up to 150-160, and still have another gear to keep the RPM in the low 5,000's at the high end. Everyone needs a cruising gear at 160 mph, right?!
