Got a clear day today with not much planned so I was able to get the car out for awhile. Started it and let it idle in the garage for half an hour or so till it finally got to 160 degrees and the ECU started its " learn" mode. Went down and got some gas and drove around for about another half hour or so. Did some neighborhood driving mostly under 30mph. Then pulled a few hills and pushed it a bit. Then made a couple hard first and second gear pulls. I've heard it takes a few trips for the EFI to get adjusted but I'm very happy with the way it's running. No cold start issues, which nice. It seems to have a bit more juice than it had with my quadrajet too so that is unexpected. Hard to imagine what it would be like if it ever did hook up. Friggin crazy! I'll give it some time to settle in before I swap distributors out and wire it up for timing control. So far I'm happy.
