Thats the cam I run in my car and you will need a duel spring in my opinion. I run the Comp Cam 921 duel spring kit that comes with retainers and everything you will need to run them. Why are you reving to 6800 RPM with this cam I shift at 6500 RPM because car dont gain no more by going higher in the RPM on the dyno or the times at the track that really matters dont do as good that high either. Hope it works out for you.

Well from a material/processing standpoint the PAC-1518 is much better than the 921. But a 1518 won't always work in the place of the 921 due to the load/rate differences. If you want the best of both worlds, the PAC-1521 is what you want. It's a 921 (PAC-1221) on steroids.

We stock the 918, PAC spring & the PRC double spring kit. For someone looking to save money the single spring is a ok option. The negatives to a single spring is your always vulnerable of a spring failure causing a catastrophic failure. With a double spring you have a longer lasting package that gives you some extra safety thanks to that extra spring being there. I've personally seen our springs after 60k miles with there pressures tested & they could have easily been run again based off pressures. Most people agree you need to atleast check a single spring every 20-25k miles.
