    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!

    Easy, not running you down, simply stating was he has shared with us already. No offense meant. I don't think there are any on this forum that believe in the converted gasser theory anymore

    No harm, no foul, didn't feel offended at all, sorry if I came off that way.

    Default Rearend

    Just going back and reading over the posts a bit. When talking about rearends it would be interested to compare the little 7.5" rearend behind a 6.2 and a 8.5" behind a 6.5TD. We have run a stock 8.5" Gov-Lok behind a 95' 6.5TD that my friend drives like a grandma. (Ya right! ) It only recently gave out. The truck has 480,000 kms on it and the rearend was put through many breakstand attempts. I was just thinking that he might be able to get away with leaving the stock rearend in if he is building a stock spec 6.2 setup. Just a thought....

    Personally...I'd do a Cummins 4 or 3 cyl swap. They are well established swaps and I've seen many of them in small vehicles including Jeeps etc. Easy to find and work on.

    Just a thought.
