I have seen plenty of engines with a little lower compression than yours run good for a lot of years. I would also run Castrol 20/50 in your engine. G.M.

Me and a friend were discussing this issue yesterday, and he said to pour MMO down the carb with the RPM's up, until the car dies and allow it to sit overnight.

Then start it the next day and go out and drive the heck out of the car. I haven't put any in the gas yet but did put in some Seafoam awhile back. Going to put some MMO in the tank.

I appreciate all who have replied to this thread.

Thanks!!
