I ran the engine on the dyno before putting it in the car, and got the best HP / Torque figures with #38 nozzles and a #45 pill. The dyno even indiacted that the engine wanted more fuel, but this was the biggest nozzles / smallest pill I had at the time.

I warmed the car up to set the timing and valve lash. It was idling for about 10 minutes and the temp was only at 110 F. In that 10 minutes, it burned about 5 gallons of alcohol.

I just made my first run with the new configuration and my oil foamed up so badly that the vacuum pump filled the catch can and forced about a quart of oil out of the catch can breather all over the engine. I know the car is running too rich. The temp at the end of the run was 140 F.

The correct intake fitting for the vacuum pump is mounted on the end of the valve cover, as recommended by Moroso.

I can build more engine temp and reduce the oil milking by increasing the pill size but is there any way to reduce the amount of oil the vacuum pump is picking up?

The fuel pressure at an idle is 60 psi and 170 psi at full throttle. Does this sound high? Should I be running a bypass valve?

Any ideas?
