I put on a FlowKooler pump that draws into the inlet regardless of rotation direction just to be safe. Adjusted my idle way down so 1200 in park and 550 in gear at a stop. Still too much drop but I don't get into temp needle red, just short of it.

No vacuum leak at all, mixture screws 1 1/2 turns.

Mishimoto, Edelbrock, Summit, and two local motor shops have all reached the same conclusion at this point: I need more airflow. The Mishimoto 2600 total CFM on these two fans is just not enough for me, probably cause of the cam.

I have 2 Derale 2100 each CFM fans (4200 total) coming along with their PWM adjustable fan controller. I'll let you know if that fixes my overheating.

Anybody interested in the Mishimoto fans? : >)
