What Diff ratio are you guys running on the street :confused: I am thinking 3.7 would be ideal with 5 speed, with 5th being overdrive (TKO-600)
Behind a Big Big block manual. Want to able to cruise on the highway at reasonable revs.
1st 2.87
2nd 1.89
3rd 1.28
5th .82

4.10 12 bolt posi with a 454 and an M22 :D not very economical :D 100klms = 3000
3.5 or 3.7 would be better or even 3.9s with overdrive would be ideal

69coupe, I'm running 3.5's with a glide and 800hp. If you're running around the 500hp with the 5 speed and it's a cruiser i'd reckon 3.2-3.5 would do you just fine :D Nice pull and long legs :)

my 69 camaro runs a 4.10 chev 12 bolt, 4 sp manual with a 350 small block again a bit to high, good around town and not to bad on the highway but 3.5 would be ideal as a cruiser. What size rims and tyres are you running on the rear ?

3000 @ 100klms/hr dosent sound like much, but with just a pair of flowmasters it's pretty anoying after about 20 minutes on the freeway :mad: Around 2500 would be nice :D

Thanks a lot, handy tool. At 60MPH I would be sitting on 2300RPM. 3.7 sounds perfect :)
