I'm gonna try 451's fuel can on the fender first so we can eliminate water in the fuel, crap in the tank, or a cracked fuel line.

Blus and Robert: It's out on the highway cruising 60mph, top gear, 1500rpm, lean into it to climb a hill and it starts. At the same time I can downshift to 2nd, wind it out to 5 grand and no problem. So the way you worded it Robert is exactly right.

Yeah Blus, it's getting more noticible with the cold. Just an external vacuum gauge is all I have, nothing in the cab. Plugs are Champions. I know what you're saying about the Autolites, I put some colder ones in my 360 Magnum and man did they ever kill the bottom-end power. Went back to Champions. I'll be off-line until later tommorow Guys, thanks for the quick replies.
