Default Motors out!

Well, motors out, heads are off, and yes it was a blown head gasket. I gotta tell ya this job was much easier than I thought it would be. I roughly have about12-15 hours invested unhooking everything hooking up to the hoist and pulling it out. I dont think thats too bad doing it all by my myself. Found the leaking freezeplug and man those water passages looked like crap!! Full of buildup.

Default My problems were.....

Mostly I was having overheating problems till the drivers side rear cylinder filled up with water. I figured it was a head gasket but I know the previous owner had run a few cans of stop leak through it in previous years. When I changed the water pump when I got it the passages were a little gummed up. So I figured that its not much more work to pull the whole motor than it was to just change a head gasket. Also when I'm done I think I can have peace of mind and trust that the car will make it across country if I want it to. Before this happened the tranny was acting funny occasionally, and I wanted to rebuild. I also have a full set of poly bushing I want to put in so I figured I got all winter to get this done.

About motor plans? I'm really up in the air about this one. I had thought about a 383 conversion, but I'm not studied up enough on the subject to understand what all really needs done or changed if I go this route. (How much machining?, Do I really need new heads? Do I have to do Headers?.) I am definately going with a super ram/cam. But like I said I am trying to study up on this to decide what I am going to do. Or the other option is to stay 350 with the superram..... My main goal is dependability with a few more ponies..
