A little update as to how the Edelbrock injection is doing. It has trimmed a fair amount of fuel out in the few miles that I have put on. I have still been trying to get rid of a low rpm stumble, just off of idle and when driving it in OD at engine speeds less than 1400. We ended up fixing driving problem but screwed up the off idle worse. But in the end got it back to what seems to be rock solid in the low rpm and just above idle range. I didn't go for another test drive to check OD cruising. Just smiled at how we learned and tuned on it with no tools. (Adjusted the throttle blades with a dime, when necessary)
We flipped the lid on the air cleaner because we were curious, and it is sounding close to a Q-jet now at WOT.
It is also feeling pretty good for a 350 at this elevation and in a 5K lb truck.
