Holley 1850-5

Well I bump stopped #1 cyl. and found the balancer off 5 degress. So i guess when I was running at 8' for 100k miles it was actually at 13. Guess that's why it ran so good prior to rebuild. Motor still not right. Also at 800 rpm I have 13 in. of vacuum not 15 as previously thought. I might try a different dist. I have just to eliminate any possible issue there. I'm having a hard time thinking water port may be leaking into intake from intake gasket and not oil as well. I forgot to spin the motor while plugs were out so I guess I'll try that next.
