Not to be negative, but I would at a minimum watch what oil you put in your LT4. I have seen soooo many blown up LT's including my 2018 Yukon bought new w/ perfect Mobil 1 oil changes. The bottom ends are built super tight and the lifters are junk. I have no idea what sort of warranty they give on the crate motors, but I would research it and have all the paperwork ready for JIC. Might give Lingenfelter, Katech or BTR a call and just ask what they recommend for preventative maintenance/upgrades. Those are the only guys I would trust to touch an LT, and this is coming from someone who builds motors ground up.
PS: If your buddy with the 71 Blazer decides to not finish his project, I am looking for one. Thanks!
