Thanks guys, I am sticking to the ole 235. The reason to change was that to previous owner or before him had a ton of Bars leak in the block,I don't know the reason and the guy I bought it off of won't call me back. I check the heater core and radiator , no leaks there. All I can think was maybe a head gasket blown. Compression is good 120- 125. I hope I can get it all out by flushing and having the radiator re-rodded and pressure check,
steve
