george trying to help

I have been searching the forums and finding little on the subject. I have a 4l60e transmission I am going to spend 1200 to get it beefed up. AI, I am hoping a 6.6 bolts up to it. What other issues besides reusing my 4.8 flex plate for 6.6l? I have a list of engines that fit in this model and years for you. But i am wondering about 6.6 knowing it will have to go on the dyno.

Ly6 The 6.2L engines listed, are for the most part drop in. Any Gen4 5.3L Engine, and the L76 6.0L Truck Engine is plug and play for the most part. You will need to have the ECU Tuned if going with a larger engine. Me personally, would remove any AFM/DOD Hardware from the engine you plan on replacing it with, and use a Non AFM/DOD Cam with the same specs, or a small performance upgrade cam.
