My 1970 Pontiac Grand Prix SJ 455. Cold start idle after sitting in storage for 10 years. I fired it up to relocate after sale of house. Dig the idle! That's how it's done boys.

Early NE Ohio day about 35 degrees. Engine has a Holley 830 Annular with no choke provision and progressive drag linkage. Set up runs at 165-170 Degrees on a 90 degree day, so it never gets past 150 running on a cold day like that in the video. Sounds even better once warmed up all the way.

Car is for SALE! (6/30/15--Car has been sold to a friend. Sigh, but I just don't have time for it. Hellcat- here I come!!)
