First --Thank You
I have the breather to go to the air filter
The rear doors and windows ,short of welding them shut will never seal real tight . The fit and seal in 1954 for trucks was not much of a concern. I did duct tape them shut once just to see but it did not solve the problem. The Primaries are adjusted about as lean as I dare the secondaries can still come down some. This engine is a little picky as to outdoor temps and how lean /rich it wants to be. Temps around here now are up and down.
The plan is to cut the tail and reroute it out a corner about a foot and test , It will be ugly but if it works I can figure that out later.
