400 or 468?? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I have a choice between these two motors. The 400 is all stock, needs some work, but will require the least amount of work to put in my suburban. The other motor is a 468 that is in my car. I want to sell my car with the motor, but no takers yet. The motor is pretty radical, alum Bowtie heads, big cam, RPM intake, 10:1 comp. If I would put it in my burban, I would change the cam to a smaller one, like the Xtreme Energy 268. Had one in another 454 in my old truck, and it worked good, and sounded good. I have the crossmember off 73-87 style, so the mounts are no biggy. I would move it forward some to clear the valvecovers and HEI. Not sure how big my radiator is, but i would probly have to get a bigger one. Bout all I would need is headers, but that isn't even a big deal, less than a $100 down to Autozone or Advance Auto. The thing is, is I want to drive this truck, it's 4wd, but not gonna take it wheeling. Don't want a racetruck, either. Gonna swap in the 4-speed soon, and I pick up my axles tomorrow. Going from D44/D60 with 4:10s to D44/12B with 3:08s. With the 468, it's in my car and ready to go. I already have the flywheel, so just need a clutch. I liked the last 400 I had in my old truck, and wanted to build this one identical to that. I'm in a toss up to which motor I want to run. The way gas is, I want the 400, but with the 468 I wouldn't really need a gas pedal, could just let the clutch out.

In the long run, it will be a hauler, want to get a camper for Bloomsburg, and the weekend outings or whatever. But either motor will easily handle that. I have pics of the 468 in the pics link in my sig, and would stay like that, except for an alum water pump and the v/c's will be red. Look just the like the motor in the background in Trucks. Red block and v/c, everything else aluminum. So what would you do???

Economically speaking I think the 468 will add more value to your Burb than it adds to your Malibu from a re-sell point of view. You don't see very many 60-66 trucks, let alone Burbs with BBCs. From a performance standpoint, Burbs are heavy rigs and can use all the help they can get. 400's are very capable, but if I was faced with that choice, I'd go with the 468 in the Burb.

I said when i first got my malibu that I would NEVER sell it, got to almost to where I want it, now i want to sell it. Go figure. I'm getting kinda tired of cars in general, everyone has one, but nobody still has a malibu, let alone one with a BBC in it. I can still find these cars around, but I've never seen a suburban like mine around here. I was in the military and got to travel alot, and the only place that I've seen some was when I was in Colorado. Like you said, I could sell the burban alot easier than the Malibu. And actually, my suburban isn't really that heavy, maybe cause I've used to my 97, which I think weighs 6500#. Hopefully I can get some pics of the process......

I had a 454 in my 1960 GMC Sub 4x4 and pulled it out and sold it due to the horrible gas mileage....I mean, I don't expect it to get 15 MPGs, but at 8-10 it sucked....besides, I have a 454 dually crewcab 4x4 to tow with, so it didn't make sense to keep that gas hog 454 in the Sub. I would stay as small as you can (cubic inch wise) and save your wallet at the pump!!!
