I was having above "normal " temps with The Pig despite new radiator,hoses,water pump,engine, blocked crossover on intake, new fan clutch etc. I have the oem fan shroud without Venturi ring. The elevated temps were only experienced at hi way speeds and were tied to travel speed. The faster I went, the hotter it got. After conversing with Jim Hupy on the phone while I was in LA looking the engine over he asked me about the air deflectors in front of the radiator and behind the grill. I had none and there had not been any there since I bought the coach. Jim described them to me and I rigged up deflectors with 1/8" plywood sheet/ rebar tie wire/ jigsaw. The temps on the way home never got above 220 and typically hovered at 200-210 no matter the travel speed. I ha seen peak temps of 240 prior even after backing down the travel speed to drop the temp. If your coach does not have these deflectors in place I highly recommend you buy some ( I hear Bert and Fay make them) or make up a
pair.

I can't remember if those went into production with the new AC system in 77 or the 403 in 77 1/2
