Just a little update on my project. The bigger radiator is a great plus. Last weekend I made it to the Saturday night meet and back. I ran a little past halfway on the temp guage which I would say is 180-190 degrees. That was in a balmy 95 degrees. Much better than the tiny radiator.
I still have that little stumble off idle and with a Holley tech I have figured it out. This ultra 570 Street Avenger carb comes with an 8.5 powervalve. That means I would need to produce 17" of vacuum at idle. He also told me any cam more than stock would have a hard time producing 17". Well tonight I put the vacuum guage on it and when all warmed up and at 750-800 rpm I produce 15" of vacuum. Tonight off comes the carb for a 7.5 power valve. Details to follow.
