a few lq4 questions I have a 03 lq4, i was wondering which heads i should go with, I have some 99 heads that are lightly ported and milled(nothing special) or should i keep the 317 heads on it? I am running a ms4 cam in it. I was also wondering if going with a ported ls6 pump on this will be fine. Will my ls1 wiring harness work with this engine or should i switch anything up? thanks for any help
Your stock harness will work fine, no changes. Physical dimensions of a GEN III iron truck block are identical to that of a LS1. Just dont forget to drill the alt boss before putting it in the car. Much easier while it's out

Brett Foote The main bracket has 3 bolts on a alum block. Iron blocks are completely missing the top left boss, so you're down to 2 from the start. The bottom is drilled/tapped, the top right is present but not drilled. You CANNOT mount an alt using one bolt down low and the rear brace and expect any sort of reliable service from it
