I tried finding one but I only came across 350 seals.

Oh interesting. So just the 4l80 and magnum did it then. I would be surprised if holley did not have a power enrichment setup already in their system. The idea is to just check that its on. Other than that lots of good ideas to work with for now and whittle it down. Cooling issues suck.
I was thinking more about this and I probably should reset the Holley EFI and have it relearn the truck now with the "new" transmission and tcase setup.4l80-e is a BIG trans and the t-conv on it is about half its weight . then add in the mix of driving threw the aux range box there is more drag .
But everybody knows you gain like 5 horsepower by keeping the oil off of the crank right?You don’t need a windage tray
It’s not a racecar Scott!
Shoot, with the rev's I'm spinning I guess I need one! That last 5 hp might be all I need to get over the hump.Not at the speeds that things turning!
But the sticker is worth 5

Half the time you have to move the camera lead in the opposite direction you want it to go and then you start getting confused about up and down.Yeah, if I hadn't thought of it earlier plus having the camera to verify, I might not have even noticed it.At least you know for sure what the problem is.
