Hello,
I just purchased a 1980 Surbuban with a Mark IV 454 that has been bored 30 over and has a Comp Cams 268H. I did a compression check on all of the cylinders today and found that the driver's side cylinders are all around 10 to 1, and the passenger side are all at 11 to 1. Does anyone know what might be going on with this engine? Head gaskets? Stretched head bolts incorrectly torqued?
Any and all help will be greatly appreciated.
