do you think we can swing 4th low range?

how many rpm? and what are your rear gears? for me thats a big gear with 3.55's and 4k

3.73 at 2500 x 3500 rpm in 4th low is it possible that it would take off

you sure you have 3.73's? they came stock with either 3.55's or 4.10's ... and what clutch do you have cuz your gonna need to slip it, I have a 3850 dual disk with the 1 3/8 input shaft

maybe they are 3.55 s its a dana 80 ive got a single disk clutch i need to go a head and get a double disk and the shaft for it but funds are tight the shaft isnt that bad but the clutch is gonna be high :argh:

how much power can a stock 5 speed hold in a 94 cummins???

yeah but you can slip a doubble better than a single I would not try 4th low with a single disk I would stick with 3rd low its an easy gear to turn only problem is its gonna be a slow gear round 20 mph. If I were you I would get that dual disk asap

the stock nv 4500 can hold lots of power, I still have the stock nv4500 in my truck the only upgrade I did was change the input shaft and fixed the 5th gear nut ( they tend to walk off).

Thank you I have a pull coming up soon and I will let you know how it goes.

Get some 435's, Silver 62 and a Valair Dual Disc. :U:

what size turbo would be good for 400 to 450 hp
