I'm looking into the NV4500... not sure what combo to brew up.

What transfercase can I use behind an NV4500? would my Chevy Transfercase fit?

the 4bt motor is the way to go. i'm not sure about the 700 tranny. i have one in a 92 chevy 1 ton and it gets the job done. if you need any info, ibuy alot of those frito lay trucks and have several of those motors at my yard. i have the aftercooled and the regular ones. they all have turbo 400 trannys behind them. i have a couple with 4 speeds. call me @ 972-877-7304

Can't you just hear the Little BT barking the tires on the 1-2 shift and the sound
from the 4" pipe............ makes for a warm feeling inside.

.....btw, cummins says that a 3.9 4bt weighs in at 680 lbs (minus the flywheel and electrics) in automotive applications.

Chevy finally got it together in '87 on the 700r4, but there is still aftermarket parts that will make it stronger. Of course any upgrade you WILL pay for.

Also if your still going to use the 700r4, there are 2 different bolt patterns.
1. standard Chevy, guess this would be standard adapter pattern Cummins uses
2. would be the 2.8 family, this includes the Caddy Northstar engine too.
and now that I think, there might be a BOP (Buick, Olds, Pontiac) pattern too for some of the other large GM cars but thinking that might be a little rare.

got...DIESEL?

how about deck height?? Is there enough room top to bottom for the long stroke?? I don't know how tall they are, but work on quite a few 4bt's mated to Onan generator sets, and they are quite a bit taller than any gas engine that has been swapped into the s-10. I assume this is also a 2wd?? Pan clearance would definitely be an issue in a 4x4.

Funny, I was thinking the same idea, but with a dakota. Have the opportunity to buy a '91 2wd. I have access to a few 4bt's being an Onan service center. Sure would be a trick pair....CTD Ram AND Dakota.

I think small blocks weigh in at 550lbs, big block are 750+lbs. Go over to turbodiesel register and you'll see a thread in the diesel swap section. A guy swaped in a 5.9 in an S-10!!!! So a 3.9 wouldnt be too bad i guess, just 2 cylinders shorter.

Well, I've gone a hundred different directions and this is what I've come up with.

I finally got my hands on a 4BT and I'm supposed to pick it up aug 6 (Excited )

Was going to go with an NV4500 and dodge drivetrain but my wallet talked me out of it, instead I'm on the lookout for a GM Flywheel and an NV3500 out of a late model s10 w/ 4x4. The 4BT I found came out of a frito lay truck and is coming with the Turbo 400 behind it so the bellhousing adapter should bolt right to the NV3500. This takes away soooo many headaches and really doesn't give up so much stength for a daily driver. It absoutely had to be considered taking into account the true use of this truck.

I've also started to build my biodiesel plant... It will be green power :-) I'm so anti "granola head" but I'm also one for using the resources around us and being self sufficient.

The S10 is currently stripped to the frame and sitting in my Dad's Garage. I'm finishing the inside of my house and have plans to move in sometime in mid-late september so I should be able to get started on it at my place at that point.

My son put a 6bt in a 95 2wd S-10. There is enough room.

We gotta see pics of that!

Dave,
I sent you some....there are a couple in my pic file in TDR, but haven't posted them here.

Jay,
How far did your son have to drop the drivetrain to get it to fit under the hood? I won't have the length issue that I remember him running into and having to hack on the firewall pretty hard if I remember correctly.

wannadiesel

Thanks, Jay. Those are some cool pics. It actually looks like it would be easier to work on than a 2nd gen, there's only one valve cover under the firewall.

Very few.
I am not sure what vacum needs the 3.9 BT has. Probably none. But you do need vacum for the brakes. aaaaak! Not really. Get a hydroboost unit from a diesel cadillac or 86 diesel full size Blazer. These brake boosters work on hydraulic pressure from the power steering pump. You probably have a saginaw pump which is more than enough pressure. Some saginaws come with two high pressure outlets and two return lines to the pump so you can run individual lines to the brakes and steering. If not, run the high pressure line from the pump to the brake booster, then to the high pressure side of the steering gear box.

Look, there is no point in going thru this right know. Suffice it to say it is very doable. Once you decide on it e-mail me or call me (703-860-4082) the name is Frank - and I will walk you thru it.

To match engine to tranny, contact advance adapters. Also, these engines were used very often to repower gm P chassis tat came originally with v-8s or inline 6 cylinders so, it may be easier than you think.
