    I have a chance to get a 454 out of what looks like an early 90's Suburban that was wrecked for cheap (like free probably). Having never messed around with Big Blocks, is this thing worth anything before I go through the effort of yanking it? The wreck was side impact towards the rear so the engine compartment is fine. The car has about 200,000 miles on it, I just want to know if this is a good starting point for an engine? Also, does anyone know what kind of tranny would be behind the 454? Thanks for your insight. . .

    I'd snag it on general principles.

    Pretty much any Chevy V8 trans will fit behind it. Not all of them will survive. If it's a 91-up truck it should have the L480E overdrive auto, if it's older the TH400 3 speed auto.

    That is what I thought, but is this engine something that I would want to put in a 1959 wagon some day? or am I just going to be storing this thing because the price was right?

    Yep, snag it. I can't remember but it may have the small "peanut port" heads that aren't that great but heck the price is right.

    It would work in a 59 wagon, and be fun to drive....not quite trad, but that wouldn't stop me.

    It has the peanut port heads, and is probably very low compression (about 7.5:1). Still, the peanut ports will produce some fun torque, and better pistons aren't that expensive. Get it. Bump the compression to 9.5:1, cam it, and have a good time.

    Might be a factory roller cam block and might have no place for a mechanical fuel pump?? If you have a few hundred bucks,buy it.

    nice thing about 454s is that even stock - you've got all the torque you need. You'll not find a better price than FREE

    this one is a no-brainer...

    get it. even if you DONT ever use it, its free, and free means bitchin swap fodder...
  12. 91 Suburban would probably have a 700R4 with electric speedo drive, mine does, too early for a 4L80E but the other trans option was a TH400.

    The motor itself will be a TBI, not huge power but probably not bad. They usually hold up pretty good even with the high milage, stay clean inside, and so on.

    Alright, I am convinced. I think I just needed some motivation to take the hoist out and go over there and pull it out! Who knows, if I have the engine maybe my wife will be convinced I need to get another car for it. . .

    200,000 on a big block, take a pass you, got deep pockets 2.50 a gallon for gas what would do with it. a 350 with a stoker kit from speedway would be faster and get better gas mileage in a rod

    I thought the 4L80E was introduced in 91, behind big blocks....and the 700R4 wasn't used behind them was it?

    Leave nothing behind!! So many times the accessories or what holds up big block swaps. The manifolds, all the brackets, motor mounts...take em with ya.

    As previously stated, even if you don't use it you'll be able to trade it one day for something else that you want.

    As long as you have some place to store it, and some $ to go thru it and add some horsepower take it.
  21. :D Naaaahhh.........this is for FUN - not a daily driver. Nothing against small blocks - but - the roar of a 454...oh yeah!!!!

    It's a no brainer. Grab it. Everybody expects a small block not a big block. As far as gas mileage, I run a 425 hp 454 crate motor with 700R behind it in my 3700 lb cpe and have pulled as high as 19.6 mpg.
  24. You're right, actually, if I would read my book. It was introduced this year for light trucks rated at or above 8600 lbs GVW. So it would depend what size Suburban this is. But I also believe the 454 wasn't available in the half-tons.
