Been doing allot of driving and analyzing trying to nail down the best gearing. Here's my thought, I don't like how high it's geared for 1st gear takeoffs because with my cam it likes to be in the 1,500-2,000 rpm range meaning you have to rev it a bit on takeoffs although not bad at all but it would be nice for town to have a lower gear. 6th is useless unless your doing 80+ miles per hour which I knew would be the case with 3:55s.
Here's my figures based on a 2000 rpm cruising speed and a 6000 rpm shift point.
2000 rpm 4:10, 4:30, 4:56 6000 rpm 4:10, 4:30, 4:56
1st. 15, 14, 13 mph. 44, 42, 40 mph
2nd. 22, 21, 20 mph. 66, 63, 59 mph
3rd. 30, 29, 27 mph. 90, 86, 81 mph
4th. 39, 37, 36 mph. 118, 112, 106 mph
5th. 53, 50, 48 mph. 159, 151, 143 mph
6th. 78, 75, 70 mph.
Mostly what I'm looking for is cruising speeds of 55, 65, 70 and 75 mph in the 2,000 range in 5th and 6th but not running out of gear in 4th in the quarter. Not that I'll really race it but I would love to get into the 12s with it someday even if it means a little more ponies.
