I have a 1969 chevy c-10 with a 400 small block in it, unknown miles. It ran fine, wouldn't really smoke the tires but ran fine, before a friend and I went through it and replaced some gaskets. It barely runs now, drives ok but won't hold an idle long and idles rough. I checked the compression and two pistons register very low compression. Someone told me the piston rings were probably bad. Recently someone said that if the lifters didn't get tightened right this could also cause the compression to be low. Anyone have any ideas? Does anyone know how tight the lifters are suppose to be tightened? Any suggestions would be greatly appreciated. Thanks.
