The AFR's did not appear or feel any different than the Speedmasters. The ProMaxx's claimed to flow 285cfm I think thats reasonable. The S.S. on the ProMaxx's were not as murdered as I've seen in the past but not great either. I was more excited to see all the stuff for the G3's and there was plenty. J.Rob
Going by AFR's performance in other areas, I'd expect their heads to be as trick as possible. Any pictures of any noteworthy Third Gen heads or new blocks?
