Anybody have anydynographs of motors running f13 or f14 cams?

I'm trying to decide between the two and I'd like to see the power curve down low to get a better feel for low end torque and power. I know both these cams are not low end torque cams, but I'm trying to see how much they give up down low.

Futral says the f13 has a 2500-6800 RPM range and the f14 a 3000-7000 RPM range.

Also, how does the idle sound on the two, or better yet, anybody have any sound files of either of the two cams?

Thanks...I'm getting close

The graphs are almost identical. I don't have a host for my graph at the moment...but.. it made 376, through a 12 bolt.. stock ls1 intake.. stock pulley.. mail order tune. From 5k-7k it holds over 355 at the wheels.... and doesn't seem to ever really fall off. I shift it at 65-6600.

And.. It ran the times in the sig.

like thacker said, graphs will be near identical. a while back scott (gomer) posted his overlay of a FM13 vs FM15 and they were spot on the same.

I am also trying to decide between these two. I think I will call Allen.

I have a copy of my FM15 graph if you're interested.

Bigger is typically always better....

Also meant to say.. I have a few sound clips of my setup, if you'd like to hear them message me @ Thacker 00 SS on AIM.

I've talked to the shop a few times and traded a few emails with Allan. Instead of me bothering him again could you post up what he says? I'asked this morning about the f13 vs f14 and all they said was the f14 has a rougher idle. They also said I'd definetely need 4.10's...I'm planning that soon anyway.

SS346LS1, I'll aim you tonight sometime...my schedule is pretty full the next few days, it's taken two hours to finish this post!!

If you want, you can email them to tim.sheets@bently.com

i called.. i wound up getting the f14 on a 114 lsa since im spraying... no spray, f14 on 112 lsa.. i called wanting the f13, and i have only 3.73's and a smaller stall right now, but im only getting a yank ss 3600.... all 3 cams, 13,14,15 all make tons of tq down low somehow...

That's the best thing about Futral cams. They make awesome low end torque and they're very drivable.

I just ordered a Fm14 from them, but I'll be running 3.73's with it. I'll let you know how it goes with that setup. I am guessing 3.73 will be efficient enough......i hope.

Cool, I have a ton of open roads around here and have always though 3.73's would be the sweet spot. 3.42's make 6th supercruise only and 4.10s are good for the track and burning up your tires real fast .

Here is the F13 Graph. You can do a search in the dyno section for my name and find out about the cam more.

You should be fine, I've been running the FM15 on 3.42's for quite a while now...

Nice numbers on the graph, that's about what I'm looking for. I'm also adding heads and an increased CR of 11:1. So I'm hoping for more, but I'll be happy with anything over 430hp...for now

I know the thread isn't about how to do a cam swap but are you guys that run cam only changing valve springs,retainers,pushrods,and possibly other parts in the heads?
I am looking for the a good cam swap as well just wondering what was involved. 430rwhp sounds good to me!
