How hard of a swap and what do I need to watch out for ????

Physically they are pretty much a bolt in. It's the electronics and wiring that will be the bigger hurdle. And virtually every aspect of those differences have an aftermarket solution. Typically in the form of adapter harness. The big thing I'm not 100% sure of is the crank sensor reluctor wheel. They changed that somewhere along the line and if the computer doesn't match the reluctor wheel tooth count, it won't run. I'm sure there is a solution for that too, I just don't know what it is.

They make an adapter to go from 24x to 58x, but I doubt there is anything to revert back to 24x.

Ligenfelter has a 58x reluctor wheel to 24x ecm converter but nothing I've seen that goes the other way.

It would be cheaper just to pull the crank and swap out the reluctor wheel to a 58x.

Part # 12559353 Summit has them for $17.

It's just a press off/on, any engine machine shop can do it.

Well at that point you might as well get some forged rods and pistons, new oil pump, port the heads, new cam, etc. I mean, you're going to have the oil pan off anyway

Thanks everyone for the info !! My 5.3 had that crappy cylinder shutdown and ate the cam and lifter .. I have a LQ9 6.0 just sitting around thought about putting it in .

I still would, just need to do the reluctor ring swap, reuse the crank sensor from the 5.3 then send the ecm to Frost and have him install a tune for it $150 and call it a day.

Bonus no more cylinder shutoff win, win!!
