Transmission and rear end combo

[Chriszz11]

Between the promotion built t45 and the built tr3650, which do you think is a better option?

I like the internal design of the T-45 better, it tends to be less notchy shifting at high rpms.

Unless you got a different T-56 first gear is 2.67. I wouldn't consider it wide ratio. I liked it a lot better than the 3650 behind my BBS. I had 3.90's with that car. But I also had a blower hanging off the front of the engine.

Sixth gear is .62. You should be able to figure out cruise RPM from there. I really wanted to swap to the .50 6th to get the freeway RPM down.

When I ordered my magnum from D&D I got the tall 2.66 first closer ratio 1-4 then the taller ratio 5-6, so I have the .74 5th and .50 6th. Car isn’t yet completed but can’t wait to give it a try
