well a little update-The guy tore down my 454 and found that the crank bearings were worn into the copper. So It was NOT a 20 something thousand mile motor as I was told. I'm glad I didn't sell it to anyone when I had it for sale. It also had an oddball piston and a different head gasket on that side so I guess it dropped a valve or something sometime in the past. It hasn't been bored and it isn't real bad (cyl.walls) But also picked up a 350/350turbo and some other parts from a 3/4 ton chassis. Got to hear it run and it sounded good but want my eng. guy to look into it while I had it out. We may do some trading if it all looks okay. He keeps my 454 and I get a rebuilt 350.
Heres a pic of when I was coming home with it.
