I haven't read the thread but what are you trying to get out of the motor
Right now, I'm just trying to get it, and the whole truck back to stock from the years of monkey business under the hood along with the electrical oddities the PO made the truck the subject to with his Frankensteinian experiments. With the head questions, I'm just wanting to know what I have, that way when I have to go to a parts counter, instead of sticking my finger in my nose, swirling it around and pronouncing, "Duhhhhh" correctly, I can do it the right way the first time. . . .
The future of the truck is that it will not remain stock on the exterior, but I want the drivetrain normal so my wife can use it as a DD instead of our 15 mpg Jeep Cherokee. I'm looking to make it a good looking gas saver! If the paint doesn't clean up well, I'll repaint it in close to the original color, then I want to dip the front and raise the rear. Put some nice wheels and tires similar to my first 78 620 (the Red one in my avatar). After that, then the sound system goes in (it still has the right side on/off AM radio that probably came with the truck in 1977), then the interior is changed and that may mean a whole new or custom dash. The current dash is a wreck!
But, all that is on hold until I can solve this blasted oil leak. I'm starting to worry about a rear main seal. And if it's that, then the engine's coming out and a reman is going in
