    question with 454\'s

    hey, i was wondering what the best setup would be with a 454.... i'm kinda trying to gear building my truck towards getting this size engine, unfortunately it would be a few years, but until then i want to put in the better transmission, transfer case for it after i hopefully get a 14 bolt this summer.

    thanks,
    matt

    What type of driving and off roading are you planning on doing?

    The options are endless. Just depending on the type of driving you plan on doing, you can build just about any combo imaginable.

    I had a 454 in a 72 Blazer. Very torkie motor. I was breaking U-joints alot. I recomened you start off by buying a 4 wheel drive Surburban (Mid-late 70's) with a 454 that is all rusted out (should be able to get one for around a grand of less) there would be all you're heavy duty parts you'll need. I'd transfer the parts over to your Blazer, and start the build up from there. That's just my thinking.

    well... even with the gas it'll use, it'll still be my daily driver... as far as off-roading, i'll use it prob for some mud but mainly trails, with rocks and stuff like that more.

    thanks,

    That will be pretty hard to find, since GM never made them. /forums/images/icons/mad.gif Until the early 90's, the only way to get a 454 in a Suburban was to buy a 2WD or install the 454 yourself. GM didn't start combining 454's with 4WD (in a Suburban) from the factory until '92 or so.

    I beg to differ... 4x4 454 Suburbans are not hard to find... whether or not they came from the factory. There are lots of them. At least here in MI.

    Don't know about factory equiped 454 4 wheel drive burbs, but they are out there, factory or not. I've seen alot go for cheap when I lived in Omaha.

    Re: question with 454\'s

    I plan on replacing my worn out 305 with a 454 this summer. Already have the engine, just need to rebuild it. In preparation for the big block, I will be replacing my 10 & 12 bolt 3:42 geared combo for Dana60/14FF in 4:10's pretty soon. My truck is already equipped with a SM465/NP205 combo, and I installed a 6" lift last fall. I plan on running 36" TSL radials, but I haven't decided on 12.5 or 14.5 width yet. Since this is my only truck (no trail-only ride) I think this is a good compromise set up between daily driver, mudbogging, and trails. At some point in the future I would like to do the doubler and 38" or 39.5" tires.

    sounds like exactly what I'm doing. A 20:1 low range just doesn't cut it going downhill or trying to crawl.
