Well, I think I have my engine as sorted out as it can be right now. The first thing I did was fix my massive exhaust leaks at both header flanges and driver side header. I actually think that has reduced temps under the hood dramatically. I have mouted a shroud that keeps air from running over the laid back radiator. I've also re insalled my
oil cooler. I know thats not altogether necessary for most street engines, but in Tulsa right now, I think its a good thing. I do think its mainly an airflow issue. I noticed earlier that with the hood proped open some the temp seemed to settle a bit. I've given up getting it to run at 185 right now since its 100 degrees at 10PM most nights right now. currently is cruised down the highway at ~195. In traffic it may warm to 210, but I think it maintains right there. If I do anything in the future, I might consider that 800HP radiator and find a bigger fan, but all in all I think I'm OK considering the rediculous heat we have right now. I'll find out at Hallett on Aug 6,7 how it handles the heat on the track. A little worried about that but I'll take a large cooler of beer in case the car overheats, or I do. Thanks for all the help guys.
