I believe a 241 input shaft will drop right into a 261/263 transfer case as that is what the guy at DP did with his DMAX S-10. Problem being though is the 32 spline shaft is quite a bit smaller than the 29 that the ALLISON has. Also I believe you can run a 271 transfer case out of a DODGE and get a 32 spline input in it.


Good to know.....Do you guys think i will even need a overdrive?

3700.00 for a OD Is a lot of money my thought right now is to run a 4 speed

plug the trans ratios into the rpm calculator on here and see if any axle ratios that are available for our axles will work out for the top end?

With a 342 gears and 5 speed it looks like 137mph....I would like to be able to hit 150mph. Now using a OD i can do this with a 4 speed and tagging 5k a 3 speed

I have no problom with 5k but with this cam i will loose power after 4200

I can get a bruno/lenco used for around 7k with the correct shafts there are lots of them used on racingjunk and pro mod forums

I would like to do this project for under 15g to make it worth while swap then sell my trans to recoup some cash

Well I just bought a used Bruno lenco 3 speed:happy2: As far as the gearing i should be shifting at 4100 and dropping to 2800 This may not work well but i can always add a case from Lenco 2.11 first gear

Rick I did a bit of research and your idea is great I didnt realize all the actual potentials they have:thumb:

Also scrapped the idea of using gear vendors for a OD and now considering using a drop box that is overdriven probably what duramax 3388 was getting at but i never looked into until Jeff said they have OD units......Kill 2 birds with one light rock:D

Running numbers in my head this can be done for less than 11000 so if I can sell my trans and Tcase i might be able to recoup some cash...hopefully


More scratch pad stuff

Donovan from aromor inc runs a Bruno lenco and it very consistant

Do they plan on turning up the power in that truck? Seems like a waste for no more power than they are making now.

So far they havnt needed too

Guess they had a good combo Ken:dontknow:

IIRC you guys where saying something about smart racers keep the power down and win races?:eek::D


I sure hope this thing works out for me, I am worried im going to spend most of the short season getting this thing worked out:(
