So I finished a gen4 swap today. Bumper still hanging but its all plugged in. I wanted to see if I got it all.

We used a gen 3 iron block. Swapped from a 5.3 gen 4 aluminum block to a gen 3 6.0 iron block. Basically dod delete the hard way. Since theres no spot for the knock sensors to go my buddy said we can just have them tuned out (hes done it before). We took the heads off the gen 4 and all the ignition parts. Literally everything is gen 4 except for the block. The truck shouldnt know any difference?
