Great story. Interesting also, as I have considered using the shop in Chico Ca to correct some issues, however I have yet to verify their abilities. Maybe this helps.

Thanks Owen, neat stuff. Your LS will have all the good stuff on it.

I can't believe that some of the companies sent a half a$$ed system to a end user as big as GM.

If anyone is interested in PFI here's an interesting thought. Years ago I saw a 1966 Charger with a 440 and talked to the owner. He showed me his dual throttle body port injection setup. It was clean and look like factory had done one it. He'd used a couple holley 4bbl carbs as throttle bodies and drilled and tapped for port injectors. As I recall he used 2 fuel pumps, 2 regulators and 2 regulated returns; one for each rail. I believe he had O2 sensor in each exhaust for tuning.
I'd like to do that with one of my BBM engines setting it up on a run stand to tune everything. That's sort of my plan for a '69 Coronet. We shall see.
