The car is getting an injected 302, possibly a T5, been thinking about a Richmond. What kind of gears would be good for everyday use. It's not going to be a racer but it's also not going to be a fuel sipper.

With a T-5 you'll want 4.11 gears. Without the O.D. a 3.55 ratio will wake it up. SteveW

I have the Richmond 5spd. For a street car anything more than 3.50s would be tough. I never could get traction in 1st. I don't think the T-5 has as low a first gear.

for the street dont go over 3.50's even then you might find yourself launching in second gear.

Depends on which Richmond you have as to whether it has a lower first than a T5. most T5's are: 1st : 3.35 2nd : 1.99 3rd : 1.33 4th : 1.00 5th : 0.68if its a T5 z, you can get it with a 2.95 first gear, which works better with lower rear end ratio. it seems the consensus on corral.net(Mustang site, more into 5.0s than anything else) is 3.73s for a T5, 4.10s for an AOD. Even with 3.73s its hard to keep it from getting silly in second, first is pretty tough... ------------------ 74 Mercury Comet 302 AOD 3:1 Will the 302 built properly this summer? wish I knew... http://members.tripod.com/red74merc

Joe, Big difference with trannys as far a gear selection. If I'm correct the Richmond 5-speed in standard form is not an overdrive 1:1 fifth gear where the T-5 will have a .63 or .68 fifth gear. I've got a T-5 in both the 65 and 66. I was running 3.89 rear gears in my coupe and first gear will get away from you very quick, 3.35 first gear ratio. I recently changed to a 3.50 rear gear and cruise the interstate at 2400 @ 74 mph. Tough decision ain't it.. Mike

unless you find a good deal on a T5, I'd go with a Tremec. they seem to last longer, handle more torque as well. Richmond seems to cost around the same as the Tremec, just a tad more than a new T5. Tremec has good ratios, similar to the T5z, and of course overdrive.
