    progress of the night

    Got the engine and trans set it. Lesson learned- Next time cut the little metal tabs off the new poly mounts for easier install!! Other than having to massage the cups down around those everything just slid in place. The trans is about 3/4" more forward from factory though so if doing again I'd prob buy the 1" rearward mounts. Now time to start buttoning everything back up.



    the AC brackets are just loosely fitted on there to give an idea of where the compressor will be located.

    Looks good . I especially liked mounting the tac in place of the cruise control box. Great Idea!
    and I call myself a mechanic...

    I just blew the 4.3 in my 92 1500 and It has a 5spd trans, I've been doing alotta research and some people say the 5.3 wont work with the nv3500 trans but based on what I've just seen i guess it does work. So all i need is a 4.8 flywheel and different pilot and throwout bearings and it will mate up to the 5.3?

    Also,Im getting a 5.3 with ecu and harness included, since im using the ecu that came with the 5.3 do I still need to send it off to be reprogrammed?

    Can I use 5.3 motor mounts?

    Just want to cover everything before I start spending money.

    Any help would be greatly appreciated, I'm 19 and I know alot but I still have alot more to learn, this will be my first engine swap.

    Yeah you will need the 4.8L flywheel and clutch kit. Also the throwout and pilot bearings listed previously.
    You will need to have your PCM tuned or it wont run. You will also need to buy LS to SBC adapter motor mounts. Can be bought cheap on ebay even.
    Good luck!
