I was looking into putting a 4bt in my gmc 3/4 ton pick up and i was needing to know if it should pull my truck good or not. Also I wanted to know how much it would cost to git it going and what I would need. If any one can help me out I would sure appreciate it. Thanks

Need more info here chief, the questions are very vague. Engine costs range from the Low $1000's up to $5500 for a fully re-furbed unit.

What exactly are you going to do with it? Tow? Offroad? Daily Driver only?

Is it 2wd? 4wd? Manual? Auto?

Well, you've got a pretty heavy rig already, I'd say in the neighborhood of 5-5500lbs. If you're going to tow a lot, you might consider a 6BT as they're they cost pretty much the same. A 4BT should be ok if you're pulling a light load. For a lot of towing, especially in the hills, the 6BT would be better suited. Check out the FAQ thread for a lot of good tips on transmissions. \

While your stock SM465 would work with the 4/6BT the gear ratios aren't the perfect setup for the diesel's RPM range (towing especially). Something like the NV4500/FordZF 6 speed might be a better choice. Do some reading, there are several FS chevy conversions on here, some with 4's & 6 cyls.

To mount any transmission to the B series Cummins you need a engine adapter

Gm Nv4500 96 or newer will bolt up to a Dodge bellhousing 94-2001
Dodge Nv 4500 94-2001

Engine adapter dodge auto or manual 94-2001


or use a Gm nv4500 with the P-3o adapter .

a twin setup would be, umm trial and error. that i know of only one guy on here has accually done it, but it all depends on your turbos. i would go with the 6bt for your truck. my father has a 98 ram 24v and with a supechips programmer he gets about 19.5 in the city. just my opinion.

Airborne,

The chevy adapter plate is very expensive. If you run Dodge stuff, buy an adapter plate off car-part.com. Get them for about $125.00 which is much cheaper than on ebay.
