Man at the smoke

been helping my buddy work on his cuda again. This is the 440 i was talking about in the past post. I can cover the specs if necesarry but what we have is a smoke problem. This is supposed to be a fresh rebuild with about 2000 miles on it. The guy he bought it off of said it had been setting for about 18 month and that he though it may need valve seals. Meaning that is smoked when first started then buned off and was fine. The guy had some ratty exhaust so you couldnt see the smoke untill he put new exhaust. man you can see it now.

It really only smokes on the odd bank, or the Driver side half of the engine. The other side is not to bad. The motor runs strong and pulls hard. I loaned him my MSD set up and that biggs 950 and it snaps clean and runns up hard to revlimiter at 6000. Any Ideas short of a freshen up to try and clear the smoke. I was thinking to check the valves and fresh plugs and give her hell. He wants to have some fun with it before he has to pull the motor. So any secrets would help.

thanks Chad
