911 Racing Valve Train
I am building a 3.4 race motor and need to decide on valves, springs, etc.
I will likely go around .490 to .500 " lift I had a few motors done with SBC Manley SS valves, springs, etc but that shop is closed. I am looking at Web or Doughrty cams and it looks like all just provide spring, retainer kits for stock valves. I looked at LN engineering, JB racing, as well. If that is my only proven option, I may go that way, but would like to hear some other ideas. I have some good talent involved and could likely re-engineer the SBC option if needed, but that adds cost and time. |

Give me a call about our package, we have spring pans and 8mm as well as 9mm retainers, our springs have room over .500 with very good reliability.
