I have some graphs but have not scanned them in yet. Had a best pull of 381.9HP. That was with 31* base timing. The top number of the day came at 180 degrees. The temp went up to about 220 for the other pulls and the numbers went down a little with heat. The only carb change we made was increaing the primary jet sizes from 80's to 81's Other than that the demon was as is out of the box.
I think I am needing to drop to a 4.5 PV. I am only pulling between 5-6 inches of vac at idle. I have a slight stumble off the line that could not be fixed with timing. If we had cooler temps and maybe made a few more adjustments on the carb we "might" have seen a little higher number. But hey 382HP for a shade tree mechanic on a budget ain't bad!!:thumbs:
The dyno used is about 14% more conservative than some other dyno's so on another I might have been looking at around 400HP at the rear. This ain't a racecar so 382 is plenty to light em up!!!
I will post my graphs and some pics of the day later.
