1970 302 restoration
My cousin restored an early 70`s Mach1 with a 302. The engine runs and sounds ok but it feels under powered, almost like it is running on 7 cylinders. When we pull the plug wire off the cylinder we suspect is the issue it gets worse but not much worse. We don't know what to look for next, we already verified the distributor, spark, and timing. This cylinder did have lower compression than the rest when he picked the car up. Edelbrock intake with an Edelbrock 4 barrel carburetor.

what are the compression #s of all 8?

70 mach 1 would not have a 302... would be a 351C or a 428

what are the rest of the details?
