Comp Cams stage 3 N/A cams valve springs

I am going to be installing a set of Comp Cams Stage 3 N/A cams soon. I use the car for road racing only. Mods to the engine as it sits SW headers with H-pipe built mufflers dumped before the diff, 47lb injectors, CJ intake, Ford racing CAI milled out to 4.150", dual 67mm VMP throttle body, UPR twin catch can setup, and it is on e85.

I am wanting to know what springs (part number would be great) that I should use the car would be shifted at 8000rpm for 20+ min at a time.

Im using these now but they will be removed because im getting a pc d1x installed next week. They worked very well for me. 8100 redline.

I would shoot an email to Comp Cams and see what they recommend or a performance engine builder like L&M..

We use a custom PAC Racing spring set for our NA coyote engines that we run up to 9,000 RPM drag racing! I think they would work pretty well for you ;) $399 for the set of 32 and we have them in stock. If you need anything give us a call! 732-780-0770

I called a few placed and ended up going with the TrickFlow part # TFS-16801-32 springs.

Those are the exact same springs i have now.. good choice!!!

I just installed the same cams on my setup, its very similar to yours but just used stock springs. Also car is for road racing and did an event this past Saturday without a hitch reving to 8200.

Hopefully there wont be any long term issues, i know some upgrade the springs but from my knowledge i think stock on the Gen II Coyote are stiffer and should hold up fine but for extra insurance it can't hurt to change them.

How do you like the cams? I was just told it would be a good idea to upgrade the springs so. I'm already there so I will just change the springs when the cams are out.

I like them a lot, just took a little bit of driving around to get used to the upward shift of the power-band. After 5k+ it really screams but you will loose a little low end grunt, overall the car feels faster though plus much smoother and revs easier.

My setup is
Cobra jet Intake
Ford Performance CAI
ARH headers and catback
47lb injectors
VMP twin 67mm
CS3 Cams
