The stock mazda 2600 head is 100% pure garbage. If I am not mistaken, the mighty max engine, the 2.6 liter, is pretty much the same engine. Check and see, I think the heads are interchangable. Looks like a nice truck either way.
FYI...disconnect that tranny from the radiator, and run it to a seperate oil cooler. Will operate at MUCH cooler temps. My last cab plus was an auto, and I never could figure out why it ran so damn hot, and when I got the transmission its own oil cooler, I realized then it wasnt my engine, it was the transmission going out, and running super hot. Yeh, it DID go out soon after I realized what was going on. But a new cooler, and an oil temp gauge would help a bit. Especially on a 2600i engine that already has temp. problems with the engine alone.
