    Help 96 truck A/C 6.0 swap

    I can't find a pic of how the frame is cut can someone post a pic of how it's done or a link to a pic?

    Also what's the best motor mounts to buy for a LS swap to the 90's truck? I see there a few options out there. Just don't want to buy the wrong ones!

    I need a computer I have a 6.0 out of a 01/02 HD2500 but I didn't get the computer with the motor. My question is what's the best computer to get? I do not it has a 24 tooth wheel on the crank. Do I just find a computer out of a 01/02 truck with a 6.0?

    Thank for the help

    I wouldn't bother with notching the frame, its worked for some and not for others then theres the issue with wiring and having custom hoses made. I did it just to find out that the lines would run out right into the a-arm mount, but if you still insist on torturing yourself and trying to do it i'll post some pics. Best motor mounts are the cheapest if you ask me, check ebay I paid around 30 I think.

    Figured I'd post them anyway, maybe they'll help someone realize what not to do. The first two pics are not mine, I believe they belonged to a member named Nitrous (I think his setup worked).

    If you're a good enough welder( I wasn't at the time) and use thick enough metal you shouldn't have a problem with it being weak, if you get hit hard enough for it to make a difference you're f*cked already lol. There is a relocation bracket to use the compressor from an 88-95 truck and I actually have one that I've decided not to use and have been meaning to post it in the for sale section, PM if you're interested.

    Ok cool... If I change over to the other pump all I have to do is get the A/C line off of a 88/95 truck and it should bolt right up with out having to build a custom line?

    I believe that's all you'd have to do, as long as the 96-98 trucks still use the same fitting size for the condensor and evaporator. You may also have to wire on a connector for the correct pump as well. The bracket I have is made by a guy named josh powers. Its made to be used with the LS truck accesories. I think a few people here have the same setup.

    That notch looks better to me than shelling out $500 for relocation kits. Any idea why Nitrous' setup worked and yours didn't? Is there a little bit of wiggle room to raise the engine and maybe run a 90 degree fitting?

    If I remember correctly he used car accesories so there was likely a difference in the design of the compressor and where the fitting attached. Idk if he's still around here as I haven't seen any recent post from him, but you might search some of his older post. From the first pic I posted it seems like we both had similar engine mounts so i don't think thats it.
