The $600 1988 Ranger project. A semi-serious race truck build.

Radiator? Check.

Big motor needs a big radiator. This one fits that description. It's a 1994 F250 diesel radiator. I chose it because it is big and has a lot of brackets on it that I can use to mount it and to mount fans.

It will probably be flipped over where the hose connections are on the bottom side.

I tried a bunch of different rads when I was chasing a cooling problem. What I learnt is that the bottom of the rad needs support if you plan on jumping the truck. Two of the rads showed definite signs of being bowed and they were mounted using the stock side frames. The final iteration was similar to yours, being mounted in the back, but vertical and on top of a crossmember. I don't believe you plan on doing jumps, just a heads up for any following this thread.

Haha, yeah no jumps.

Been thinking about what efi system to use in this thing and I think I have finally decided on using a Holley Terminator X. I considered using some sort of a Megasquirt variant, like a MS3 Gold Lite from EFi Source or something similar. The Gold Lite looks like a nice piece and would likely be an excellent choice for a plug-n-play setup. However, this is no where near a plug-n-play situation. The Terminator X kit includes a lot of features that would be add-ons to the Gold Lite. Built-in wideband, wiring harness, and touch screen are the most notable features, but probably the best is the ability of the TermX to use a Holley or MSD dual sync distributor for crank and cam positions. The Gold Lite would require me to fabricate position sensors to fill these roles.

The other feature that is very appealing is the overwhelming popularity of Holley EFI. At any event, there are plenty of people that know the system inside and out and can provide tuning or technical assistance if necessary. They are currently on sale, so I might pick one up through Speedway Motors. Speedway gives you points toward future purchases so I can use those points to save even more money on a dual sync distributor. Whoo hoo.
