Re: big block with 2.73 gears and 400 turbo?
I just joined this forum, for the 12 bolt information, and found this question while looking it over. I am running a ZZ502 in a 65 Impala, I know it is a heavier car, but here is my info. I also have a Richmond 5 speed. I am running 2.56 in it now. I used to have a 3.08 but shredded the ring gear. Anyway, with the gears in it now, if you are running it hard, you will fall out of the power band between gears. With th 3.08's it was pretty good at staying in the power band, but I would think with the t400 with only 3 gears, you won't be happy if you want to mash the pedal a bunch. Realize that the ZZ502's have all the torque and power in the world, there are still some considerations at the back end. I am assuming that you are going to use a ZZ502EFI from your signin.
