This is a higher mileage engine and the compression was checked before going into this. The cylinder pressure varied amongst the cylinders and ranged from a high of 145 to a low of 130. I thought I posted about these numbers and whether they would be ok, but I can't seem to find the post. Anyway, from what I gathered on other similar posts, my compression while not great was not all that bad. I believed the engine to be in good enough condition that it could take a mild cam along with the new timing chain, intake, and carb. All advice on timing including vacuum readings will be considered and we'll see how much additional it can take. I believe the pump shot is still in the stock position and we can play with that some too after the timing is figured out. It doesn't have any off idle stumble under moderate throttle or anything like that, just bogs when you try to open it up. This car runs great and could be driven all day long but just simply has no guts.
