I'm
100% with Rob !!
My L72 in the 'Scayne has NEVER gone over 180*, and that is after a full pass, on the return road of the track. If I stage it at 140*, it seems to run the best. I have the original radiator, a replacement clutch, and stock fan. The shroud was cracked when I got the car, so I don't even have that on right now. I DEFINITELY concur that fuel-type is a big factor. I run Torco most of the time, and it really keeps the temps down.
