FM13 dyno results best pull was 400.2/372.9. I guess I'm a little disappointed as I was expecting more and also have an unexplained dip in my dynograph around 6300rpm's. Could this possibly be valve float? 
I am using Crane dual valve springs from my previous cam and they have about 7k miles on them.I probably won't be able to post the graph until tomorrow. Any ideas?

I say congrats! Get the kink at 6300 worked out and you're set.

I am running the F11 with all the bolt on's, numbers in sig. Allan Futral tuned my car and its trapping at 116-117 every pass, I am running the 918's and my car falls off at 6500. Allan suggested running the 921 Crane duals in my case. I have a depleted mod fund at the moment HS rockers also.
HS rockers also. What LSA and ICL is your cam on? I ran that cam on a 112LSA 110ICL and it peaked right at 6300rpms. 474rwhp 422rwtq with the mods in the sig. That was running the patriot GOLD dual springs and I didn't have any float all the way to 6800 where we stopped the pull.

I have been considering running this cam in my car sometime in the future. Does the 110LSA have more horsepower than the 112LSA? What specs with this cam produces the most horsepower for this cam? I have an auto and is not hardly driven on the street. Your assistance with this question would be appreciated. BTW, nice numbers for your car with this cam.

Dude you're on ****** crack if you're disappointed with an FM13 making 400 rwhp on stock heads....
That cam is a mere 230/232 duration cam, nearly half of most 400 rwhp Cam-only setups....

By the way, those are real good numbers for a cam only. Some h and c cars don't have that much power. Does your car idle good? Which specs for cam give the most power. cheers................

Regardless, those are KILLER #'s considering the small size of that cam and the driveability it offers. FMS is bad ***....

Gomer.....thanks for the reply. I have a Yank 4200 now. Does Alan Futrell have a cam just a little bit bigger than the F13 just for a little bit more power since this cam is small compared to others out there.

I think 400 to the ground is great man. Get some springs or whatever is wrong fixed and you should be right on par.

Good luck..
