Has anyone swapped a LM7 or similar gen in k2xx

Im wondering if anyone swapped a lm7 or something equivalent in the newer k2xx body.

People that have, have only done it because it was a roller chassis. You can't swap something in that old and have anything else in the truck function.

The LM7 was controlled by a P01 or P59 computer, the L83/L86 by a E92 computer with can-bus and direct injection. Nothing is the same between them and the LM7 can't be run by an E92 computer.

Oh i see. Thanks for the reply i was just curious to know since i have a lm7 in my storage wondering if my l83 kicks the bucket if it was swappable. The lm7 when it was in my gmt800 was flawless.. I did not do a afm delete just coded off. I already have the thermostat bypass for the trans. Would you recommend anything else? To prolong lifer issues its a 2014 with 220k miles

If you're not going to delete the AFM, the best advice is hold on and hope for the best. My truck has 279,000 and still going with the AFM just turned off. At that mileage though I'm just going to engine swap if and when they do fail.
