    A buddy of mine in Indianna is going to college and he says he can do a 700R4 for 820 shipped, depending on how much he gets the trans for.
    Is the only difference between the gas and diesel 700R4 is the torque converter?
    He says it'll have a shift kit and stuff.
    Good deal or pass? it'll be a rebuild transmission.

    I'm still wondering what transmission would be easiest to adapt in. I'm thinking 4.3L V6 s10 trans (will bolt to the diesel), its just finding one is the problem...

    I'm pretty sure the S10 v6 5 speed (New Venture Gear 3500) is my best bet.
    Just gotta find one is the problem

    Not sure that the NV3500 will hold up to a diesel. The diesels had the NV4500. Should be fairly easy to turn up one, though. They were in quite a number of applications.

    Well I was sent a link to a guy on another forum who put one in his sierra or soemthing, it had a 6.2

    I don't know if a automatic would be better, but ..
    all the work to put one in plus I'd need to covert the gasser transmission.

    Guys, this swap will go ahead, but very slowly. The engine will be delivered when it can and I'm not in a rush. I'm going to gather up the parts. I will start to look for a transmission.

    Default Tranny

    The NV3500 should do the trick. Yes it is smaller than the NV4500 but here is how I see it.
    The truck is much lighter than your typical 6.2 application.
    There is no transfer case and front drive shaft to push
    It is a N/A engine
    And he won't be towing much with it.
    In my buddys truck(1995 2500 6 bolt), he has the NV3500. It is a Ext Cab/Short box 4X4. It has the TBI 350 which is rated from the book for 1995 at 225HP and 320 torque, and he has done a few things to make the engine "Healthier". He has towed between 5-6,000 lbs with the truck over the Coquihalla highway, which anyone who has driven knows can have some very nasty grades. The tranny has held up fine. Keep in mind that his son has driven it, I drove it repeatedly, and it was formerly my brothers truck, so it has been mildly thrashed on.
    The NV3500 will do fine behind a 6.2 in a light truck. We have 3 or 4 sitting in Pick Your Part.

    Default Nv3500

    The NV3500 has a torque rating of @300ft/lb. I decided against it for my 6.5 NA engine. If your engine will not exceed 300ft/lb you should not have any problems with it.

    Default 6.2

    Most power rated from a 6.2 is 280/factory torque. I think.

    I've been thinking if I got all the parts from a V6 S10/Sonoma, a Nv3500 would drop right in.
    I haven't been able to find one yet.

    Kinda thinking of something a bit stronger.. maybe Turbo 350, Turbo 400, some manual trans...

    Hey 6.5 DD,
    is there any 6.2s that have stuff like alt brackets and pullies and stuff out your way?

    There is one complete 6.2 sitting at PYP as far as I know.

    Default Isuzu Trooper Diesel?

    While the 6.2 may be the most practical & cost-effective, I recall that Isusu offered a diesel option for their Trooper. Did anyone have any experience with that rig that they would care to share?

    Might be a bit smaller & lighter than a 6.2, *IF* you can find one reasonable.

    Just another thought. Good luck with your project.

    I would ignore those guys at the S10 forum, they've made it more than obvious that they haven't a clue what they're talking about.

    As I'm sure has been mentioned on this forum, the 6.2 was designed from the ground up by Detroit Diesel as a Diesel. The 6.2 (6.5) if pushed, will make about 300 horses and still be reliable. In the end they are very reliable engines, can make decent power, and are realitivly cheap and easy to maintain.

    I'd say go for it and run. If you can find the room and money, maybe even through a 6.5 turbo on it. Good luck with it. I think this'll be one awesome truck.

    Default 6.2-300hp

    Only thing is, he is trying to keep this as low cost as possible. Building a 6.2 up to a real 300HP would be a decent investment when it was all said and done. Not to mention, by going with an engine that hot, he is going to need a stronger tranny, axle...

    If you notice, I didn't suggest for him to build it up that much, but rather mentioned it to disprove all the guys on that forum he linked to that said it was a POS converted gasser that made low torque with low RPM's, no horsepower, and was gutless.

    I agree with R/C on the opinion of the "information" you're getting over at the S10 forum. Anyone calling the 6.2/6.5 a "converted gasser" obviously has no experience with them.

    About the only valid information over there is concerning what motives you have for doing the swap. If you're looking for fuel economy, you're likely ahead leaving it the way that it is and freshening things up a bit. Figuring the time, money, and engineering that will go into such a swap you're never going to recoup your expenses in mileage.

    If you're looking for something unique and looking for a project for the sake of doing a project - by all means go for it!
