    so tomorrow im picking up a 76 gmc 3/4 ton (1 ton rearend) 2wd pickup with a 454 in it. 112k original miles.. newer tranny, pretty decent for its year. what can u guys tell me about specs on this motor?? hp and torque wise?? i'm way curious as i am picking this up for $800 and it comes with a camper (the ones that have a sink, frige, stove, 2 beds or so etc. and have 4 legs and can pop right off the back of the bed) so im pretty stoked!! :D

    any details?

    not to bad i guess.. more hp then my 6.5, but less torque.. i guess i cant beat it for $800 bucks and being a new tow rig! lol.. who do u think would win in a tow contest... 76 chevy longbed 3/4ton 2wd or a 1/2 ton 82 k5 with a 6.5l diesel n/a, locked rear end in 2wd just to make it even.. :p:

    thats what i was thinking too. do u think the 454 will have any trouble towing the k5 around? now that i have this other truck and i can begin to do things to the k5 that i have been wanting to do ex: boatside, cage, etc and before it was hard to do these things with it being my only vehicle and a dd

    454 will pull anything you want ot pull.... it will just get about 7 mpg with a full load

    I would rather pull with a 454 than a 6.5 oil burner. You will like it.

    Mmmmm, not so fast there. I would highly bet a late model 6.5TD would outrun any stock late 70's 454 loaded down in the hills. Plus, it would get twice the mileage.

    I've got a Vortec 7400 in a C30 of mine, but it can't even come close to my diesel.:bow:

    That's comparing apples to oranges!!! The 70s were the highlight of the smog years, and when the 6.5 TD came out, it was built with towing in mind. I've owned a handful of 454s, they all were pretty good, but never owned a deisel, so can't really comment on them. I do know that my old 97 with a Vortec 454, loaded with a D60 front, 2 454s (complete engines), a welder, tool box, and who knows what else in the bed, and towing my old 90 on a dolly, never dropped below 70 with the cruise on, coming up 83/81 from DC to NYS. Filled it in DC, and went the whole way without filling. Think it's 325-ish miles. I'd like to try a deisel, but need to know more about them. As for this 76 and K-5, my money is on the 76.

    80's were the top smog years, 70's had it easy compared to the 1980's, BIG TIME. :rolleyes:

    The 6.2 was really designed for fuel mileage, since the 6.5 is based off the 6.2, I won't say it was designed for towing primarely myself.

    Try out a late model diesel one of these days.... you'll wonder why you ever bothered with a gas truck.....;)

    the 454 will pull anything you want it too. Using a 1 ton chassis to haul weight with just makes more sense. But you are going to sacrifice the pocket book for it. 7 mpg loaded, maybe 8 when its empty. If you could put the diesel in that thing now we would be talking! Diesel engines rule the towing world when they are used in the right application.

    My only experience with 6.2/6.5 diesels are in trucks owned by Uncle Sam and they are usually absolute dogs. Many times I wished for even a 350 in place of them. I would like to drive/tow with a either of the GM diesels in a civy truck to see how it stacks up against the gassers. From my understanding of the original post he is going to use this 454 to tow his K5 around with. From my experience I would be happy with a 454 for weekend trailering of my K5.

    The modern diesels are a whole different story. My buddy has a short box CC super duty and it will drag 10k around at 70 like nothing is behind it. If I were in the market for a new(er) truck I would look very seriously at a diesel.

    no way! i love wheeling with the 6.5 in the k5, its so awesome wheeling all day and only using a 1/4 tank of gas while everybody else uses all kinds. and i just love the huge amounts of torque compared to a gasser :wink1:

    Yeah I can plow all night all with my 6.2 and only use 1/4 of a 20gallon tank.

    As the Current owner of two 6.5 powered trucks and 3 454's two carbed and one Vortec I can say that the 454's pull much better than my 6.5's . But the 6.5's are very good mileage wise

    And big blocks sound better than those old diesels anyways.
