Thanks for all the help. the timing is set at 35, there is a t-stat in it with the center out of it, but I do not have a shroud or fenderwells in it yet. I tried setting timing at 30,slowed down and ran like crap. never went anymore on timing since :?: I've only raced the CUDA about 3 times this year do the temp problem, some people say that temp is find, I don't like it. thanks roger
