So it is possible to have an issue...or not. But it is totally doable either way. Just be prepared in case.
Well that doesnt sound too fun lmao

Yeah I know. The down time could be a couple or 3 extra days. Since it's my daily that's why I put it on hold.

I would look at the LT4 gaskets. My guess is they fit and they're similar build to the LS9

Ya gonna cam it also, just gotta figure out fuel side to handle the power I wanna make w this truck.
Ya people delete VVT on these also, I guess it depends on the plans for the truck if they keep it or not.
Cant have a 7 sec car and not have some power in the daily/garage queen truck lol

So how much power can the stock fuel setup make on these?
and the transmissions hold up fine to that kind of power?

Gonna run the stock fuel setup for now and see what it shows on the dyno. The cam I got has a 38% fuel lobe so Im hoping that will help on the hpfp side of it since the LT4 pump doesnt fit without alot of modification from what I heard. The in tank Ill run also till it shows that I need to change it. Ive got backup plans in case I need more fuel

The trans side of it Im not sure on power levels so we'll see how that goes lol
