Milky
Sorry guys, but I mis spoke on the SRP alloy for BBC high compression. It is not what I said. It is 2618 just like JE. Also it is not on the box but is in the literature. Oops.

If you do bail on this engine and go another route, there is better shops to choice from then Schmidt also :wink:

Cold
Compression test: 195 to 218 psi
Leak down: one cylinder at 0% and one at 2%. All the others at 1%.
Hot - 160 degrees
Leak down: 3 cylinders at 1%, 4 cylinders at 2% and one at 8%.
I changed to oil after the tests. It looked good. No milking.
Warmed the engine and checked the valve lash. All were good.
The oil in the top of the heads had no indication of milking.
I also cleaned out the vacuum pump, lines and breather tank and changed the drive pulley. The vacuum pump is now spinning at 75% of engine instead of 50%.
Now I am wondering if I am rolling into the burnout box too cold. And the initial hit of alcohol washes the cylinders and dumps into the pan.
I would rather not give up on the alcohol now that I know the engine is tight.
You guys say you are running 39 nozzles and 80 - 85 pill. I run at a normal density altitude of 5500 - 6000 feet. Shouldn't I be quite a bit leaner than you?

If I run 39 nozzles with a 100 pill, that will be a far cry from the dyno that liked the 39 nozzles and 88 pill. The difference was that on the dyno, the engine temp was always above 150 F.
