    96 S10 5.3L LS1 Swap with stock 5 speed

    Hey guys, i have a buddy that has a 1996 S10 4.3L/5 speed that wants to swap in a stock 5.3L engine and reuse his stock 5 speed, and i wanted to find out if anybody has done this, and if so what all is needed to make it happen?

    Thanks

    I think that the bellhousings are different
    LT1/4L60E/Shaved handles, emblems, antenna/5-4 Drop/16" Xtreme Wheels.


    In 1095, Pope Urban II commanded the beginning of the most heinous period ever documented: The Crusades. While killing over 100,000 Turks in 1098, the Christians "did no other harm to the women found in [the enemy's] tents - save that they ran their lances through their bellies," according to Christian chronicler Fulcher of Chartres.

    a NON LSx trans will NOT fit and LSX block

    the automatic guys can do it but not the manual guys sinc the input shaft will be to short to ride in the back of the crank

    well the auto guys run can run a crank spacer to space the flexplate out enough, but that wont help a manual guy since the input shaft wills till be to short

    ls1 input shaft length


    lt1/standard SBC inputshaft length


    notice how the LS1 shaft is longer. its because the LSx block run a recessed crank

    my buddy got a complete 5.3 w/ harness and acc. for 300 bux and he was going to do this but somone offered him 700 for the engine so...

    But he did do some reasearch, one of the things he was having trouble with was flywheel or flexplate. You have to make sure about the number of teeth, and also if its internal or external balanced. Doesnt sound like a big problems but when he was looking up all the new parts he was having trouble matching stuff up via engine size 5.3/or 5.7 ls1 and years ect. I can get the specifics if you need to.

    You'd thing all those ls engines are all the same parts but they arent.

    I just came up with the idea to swap a lsx into my 92 sonoma, and would like to use my t5 trans. I saw this thread and was wondering if anyone knew if its possible to swap the input shaft to a longer one? I've rebuilt a few t5's and it wouldnt be hard if I could find the right shaft.

    X2 Thats why I stuck with the older V8, a lot easier to match up stuff. I love challenges, but some things I just need to keep simple, due to time constraints. But all you young fellows probably have more time and energy lol.
