I just bought a 2004 Chevy 2500HD with a LB7 engine. I have a few questions...

1). What tempature should the engine run at? Loaded & unloaded. (if different)
2). What should the oil pressure be?
3). Tranny temp.?
4). EGT temps?

Prob 180 to 210 dependant on amb temp
40 plus at idle when warm to 80 plus at rpm dep on eng temp
100 to 120 when cold out unloaded up to 200 or so pulling hard when it's hot out
With probe in manifold stock I saw 1100 alot. When I installed my PPE I can get up to 1400 but have to stay in it hard on a larger tune. At highway spd on 120hp 6-700 even pulling a trailer on decent size hills at 75-85 mph rarely over 1000
