1982 C/K 6.0L Caitlyn Mall Crawler (Interior time)

Overview Gallery Discussion
Got the fan temp wired up on a switch to test, also fixed an oil leak I found from the dipstick tube.

Going for a test drive in a bit, hope it works out I don't want to have to move the cooler or add another if I can avoid it.
 
Went on a 42.6 mile test, the oil leak is fixed and the transmission got up to 190... I need more cooling it will never work when it's 115 degrees out side and it's only 64 today.


For some dumb reason I occasionally get a POP sound out the exhaust when the truck is around 29 degrees of timing... I think it could be the plugs I put in for the boost, I believe they are 2 colder then factory, but I'm going to pull one shortly and take a look and see how it is.
 
Looks rich. What compression ratio are you running? I run 6s in the 6.0 and those were my driver plugs for the 427.

What ever stock lq4 is, not sure what it is. I have been taking fuel out of the tune sense the afr was crazy with the map sensor.
 
My little bro lives down your way. Just put a new 6 sp auto in his 2015 2wd tahoe. He gutted that pos trans cooler thermostat thing they run and put a 13 row stacked plate mishimoto trans cooler in place of the factory one in front of the rad. Thing would barely hit 100 degrees driving clear up here to Utah. He completely covered it in cardboard. Now it will hit like 124 degrees. All ready for towing and good old Phoenix summer heat. Never seen one run that cold.
 
Did some spirited driving…

Can’t hear the pop but it barely does it now. I got new plugs when did they get so expensive?

Truck is getting 11.3 mpg and the tune is going off to @folkenheath to sprinkle in a little magic and see how bad my tuning skills are.

Put a mishimoto in my f350. Designed to keep 60deg above ambient and it does. It's huge though. Almost the size of a squarebody rad. It also gets airflow from the front of the truck/engine fan.
 
My thought is that the air under the bed is too hot due to engine, transmission and exhaust heat. I know that the floor of a truck bed can get hot enough to burn skin, depending on conditions. Had a buddy inform me.of this decades ago. He was riding in the bed of my truck, while we drove up Casper Mountain. That truck had tailpipes exiting in front of the rear tires. The old '72 K5 would get the rear floor too hot to touch with rear exit tailpipes.
I understand why you relocated the cooler, but I just don't know how you will make it perform good enough there.
Just my opinion.

That’s what I’m afraid of, the cooler is on the opposite side of the exhaust though.
