Radiator is a custom built from a shop here in MI. Two guys in the group I run with have this set up in their jeeps with v8 engines. There is a guy with an LT1, and another with a 5.3. Granted they are different engines and stock then what I run.
I changed the pump to a 6 blade the other day and welded a plate to the impeller to help with cavitation at high revs. On the street it cools the same. With no stat and driving its around 190-195. When its 80 ambient temp my hood temp gets to 120.
I shot the upper rad. hose and it reflects what the gauge shows. The lower hose is around 15 degrees cooler. The radiator is consistant with no hot spot on the front. I used an IR gun for this.
Total timing i still do not know. I shall try and find this out soon. I do not run any vacuum advance as when I did the EFI, the ford 5.0 TB does not have a ported vacuum port.
The cam I am running is:
http://www.summitracing.com/parts/HRS-712221-08 with 1.6 rockers so the lift is not what is advertised.
I have never ran race fuel. So your saying race fuel will run cooler??
