I just went out and took mine out of hibernation (8.97:1 493 .509 108 LSA). I have the Holley Commander 950 Pro TBI. Turned the key, let the fuel pump do its thing for a couple of seconds and it fired up and idled like I just shut it off yesterday. It's been buried in a snow bank since December.

Mine didn't care for all the overlap in that cam at first when trying to get it to idle closed loop. Too much reversion. It idles in park with 11" and 8ish in gear. An EFI guru buddy of mine solved the problem 99% by setting it to run Alphanumeric at less than 1800 rpm.
