Al I know we restricted the oil coming up with a plug, the pick up for the vacuum is on the passenger valve cover about 5" back in the center of the valve cover. I will get a bung welded into a cover soon, so I can get a vacuum reading.
Jim, I really wish we had more opportunities to run all out (1/4 mile) The 1/8 is great for running a lot of days and runs as well as 60" T&T and all, but to check converter slip and high speed by passes etc., the 1/4 is a must.
