Been chipping away at this in our very limited spare time.
Still not settled on a radiator. Due to the chevy steering box location and the IDI engine fan sticking down so far a drivers side lower radiator port would be really difficult to plumb. So current plan is to use a Chevy radiator that at least fits right, and plumb accordingly. Still shopping around for a radiator with correct port sizes.
Other than that, fuel system is plumbed, exhaust pieced together, shift linkage adapted, dipstick tubes bent to fit and driveshaft installed (DS from the van was a direct fit so that's nice).
Any ideas on where to find a wiring diagram for the Chevy? 88 c2500
