I hadn't checked the compression since I did the rebuild. Sure enough, the max I can get out of both the front and rear is 70psi. I installed a fuel pump cut off switch and it's working pretty good so far, just leaving it off until it's running then swith it on and it keeps running. I'm letting it run at elevated idle, about 15k for like half an hour at a time to try and break it in a bit. It seems to be running better and better. One thing I'm seeing now is the oil pressure drops after it's warmed up a bit but I think it's a combination of the pressure sender and the oil is thin - I think it's got some gas in it. I'll get a new pressure sender and change the oil, hopefully that'l do it.
Thanks for the help.
