Yes. Tr6's at .035" should be fine. The water nut?

 

Tasca probably is your best bet. I order a lot threw them

 

Edited.
I guess technically the nut on the fan clutch.
The manual says the shroud cover should state if it is reverse threaded and i remember Dave saying his was reverse threaded so I was curious

 

yes its reverse threaded. Great time to switch to e-fans

 

Ok thanks.
I'll run the factory clutch fan for now due to cost and simplicity.
Switching to Efans later.
Also strapping a couple of 7" fans to pull air through the Heat exchanger. Going to just run them on a cab mounted switch to run during hot days, traffic, etc

 

Gotcha sounds good thank you.

And I definitely recommend switching to efans it helped my milage out and throttle response

 

Planning running these to pull air through the HE http://www.amazon.com/gp/aw/d/B00H29...7JL&ref=plSrch Why are we doing this @charliedyal
It's so expensive

Any news engine plans @carcrazygts2

 

just worried about the reliability since several members had issues with them on stock and modified trucks

 

Umm I have a 4v that needs new heads. I'm diggin into the electrical side of things at the moment. May venture towards a coyote swap. Just maintiaing the old pig and saving for vacation at the moment.

 

There are deals on the 5.0L truck engine that is tempting.
I've never driven the 5.0 so I don't know how they compare to a built 5.4.
Why do you need new heads?
