so last night didnt go as planned.
started off swapping fans out, had a big dual fan set up that i made work. it hangs over the side tanks a bit and i had to cut the bottom corner to clear rad hose. it moves something like 4000cfm so thats a plus
wanted to test the new fan make sure it was working and no issues. fired up the truck and it ran for about a minute then just shut off. fired it back up and ran for 30 seconds then shut off, did this about 3 times then just would not start at all. so swapped my new ignition box that has maybe 10mins of run time on it for an old 1970s one and truck fired right up no problem
figured with the new fan working and having the old ignition box in and working i would drain the oil and swap in the shit box 20/50 to see if the rear main leak would slow down enough to wheel this weekend. as soon as i started to loosen the oil drain plug coolant started to come out
might just be an intake gasket but between that and the rear main ive decided to just pull the motor and put i back on the stand and do new seals and gaskets and probably bearings as well. will deal with the leaking block heater at that time and toss new head gaskets at it as well. maybe a cam if got the cash
