I just recently got a 2001 LQ4 with 80,000 miles to swap into my 99' 1500 Silverado Z71.
Paid $950 for it.

My only concern on this swap is that the motor might not fit on my stock trans because of a crank issue. I am a little clueless to this, but I remember reading that there was something different about the early motors.

Does anyone know if this engine with be a direct swap??

I was also wondering if there is anything I should do to this LQ4 before i put it in other than a generic tune-up; Ac-Delco plugs, wires. I do plan on getting the PCM tuned, although i dont know by who yet.

Also, what king of MPG are you guys getting out of the 1/2 tons with 6.0's??


thanks for the help,

Aaron
