Engine Size: 302
Refrigerant Type: 134
Country of Origin: United States
I have recently begun an engine swap in my 1977 F100. I am installing an EFI 5.0 (hotrodded 302). I am retaining the modern serpentine system and want to utilize a modern AC compressor and several components. I have built the rest of the engine and its components to 87-93 mustang specifications.
My current thinking is to utilize the stock (to the truck) controls, evaporator and condenser and source new the drier, hoses, expansion valve etc. (if I missed anything). After I have it installed and assembled a friend who has access to a certified shop (dealer mechanic) will charge it, check for leaks, etc.
Is this going to be possible? Does anyone know what challenges I will face?
Note: This is my first AC unit but nowhere near my "first rodeo." I am attempting to keep this post brief and I'm afraid that I'll sound like an idiot here
Thanks for the time and any advice you might have for me!
Hi Jim; One of the pros can help on the compressor, but do not use the stock r-12 condenser. Since you are building all new, use an aftermarket r-134 aluminum parallel flow condenser, the largest one you can fit in front, available here on home page. Much more efficient, and will give you colder temps inside.
I second using a larger condenser for R134. Did it on my 70 as well. Everything else can be left the same as long as you update all new O-rings and clean the system.

This is good news. Since all the parts will be "new" (or reman) I'll be sure that they have the appropriate o-rings and I'll source a new, compatible condenser instead of the old one.
Thanks for the answers, I'll repost/update when I get it all installed and charged.
