[QUOTE="swampratt, post: 2811053, member: 15054"] Also do the drive and decell thing and see what you get..it sucks oil up onto the rings and may work. Whatever you do ..do not make the cylinders rough again..they look rough . I would bet after running it they are slicked down and ready for some rings. My current 350 is on it's 4th set of rings and pistons..and never been bored and crank never turned..No ring ridge either..kept the oil glazed cylinders and No hone taken to it after the 100,000 miles it had on it doing duty in a 1969 station wagon. Buddy said i needed to deglaze it..BS i said. I bet him 45 bucks the rings would seat instantly. I broke the cam in and then removed all plugs and did a cranking pressure test 245 on all holes. Yes 245psi..I did it with throttle closed also..makes about 10-15 psi difference. 12.02 compression with a flat top with 5.5cc valve releif's .028" piston to head ,,that includes the gasket and a 54cc chamber. Comp flat tappet 270H..Got my first 12 second pass with it ran it with ported cast iron ex manifolds and ported iron Qjet intake with a single point firing it all off with solid core wires and champion plugs. OLD school. [/QUOTE]
