Well I talked to my brother that builds big block chevy engines about my problem. He agreed with me that 150 PSI compression was a tad high for 87 octane gas. I got 5 gallons of 93 and dumped a bottle of octane booster in it. After that I couldn't hardly get it to start and when it did it sounded like a JD. Got the non contact thermometer out and #1 was cold and #2 was barely 200 deg. It had what appeared to be be new Champions in it but they were junk. Headed up to TSC and got new plugs and she runs pretty sweet. Seems to idle pretty rich but I think that is because the motor is built up some, I has some serious vacuum at idle. I have a leaky hydraulic line to fix and the tin is going back on. Gonna try to do some hay this week.
On a side note I came up with a couple hundred gallons of 100LL avgas. Don't ask me where I got it!!!!! I was thinking of running this in the old 400. I have heard people say that if I run it straight I"ll burn up the motor and other say that it will be fine. I can get it for about $1.00 a gallon!!!! It is recovered product so it cant be used in aviation but it's still pretty blue!!!
