Default RE: Severne mast

Hi all, I've been using Severne race masts, ( S-racing 490, 520, & Redline 550) in NP V8's for a couple of seasons now and I can confirm that the performance is very good, better than the X6. The only drawback is cam rotation is not as good - kick & punch. I also know of a person who was using X6/X9 in Overdrive, and also had a great result.
