Well, I finally got the motivation to start working on the cruiser again. And poof, the motivation vanished again.
In February, my wife and I made a trip to England. I had just reinstalled the engine a couple of weeks prior, and was working out some bugs to get it running. While we were gone, we had a winter weather event... where it got down to about SEVEN BLOODY DEGREES! Seeing as though I wasn't planning on a freeze and planned on further flushing the cooling system. I only put water in the radiator/cooling system.
As luck would not have it... during that freeze event, the truck was parking on an incline. Only one freeze plug was pushed out. Knowing that this was bad, I lost the motivation to do any further work on the truck. So yesterday, several months later, when I regained that interest, I went out and filled the radiator and then started the truck. I ran it for a few minutes and although it was running at a high RPM (1500-2000) It was running smoothly with little noise. But I checked the dipstick, and sure enough..... milk shake. I'm going to change the oil with some cheap stuff and see if the block really is cracked... crossing my fingers at least.
Otherwise, a few months from now, I may install a Vortec engine of some sort.
