Just wanted to update this, while the Demon is on the 360 la engine in my dodge pickup, and not on the smallblock monza in my car I've been running it on the truck for months now with no issues, I still need to adjust it as it does run a tap rich but i didn't want to fool with it in the winter or early spring, rather it runs too rich than to chance messing it up. truck starts good ( needs 2 pumps in the morning) , runs good idles much better than it did, accelerates very smoothly. I've been very happy with it. just thought I'd share this in case any one was debating using one.
