I've been searching through the dyno section on these 2 cams and they seem real close in power (~5-8 rwhp) on average. Unfortunately there are a lot less F14 results than F13. I'm just trying to figure what would best suite my needs. This isn't a high rpm drag car, I'm looking for a cam that'll peak around 6200-6300 rpms considering I'm on stock 2000 rod bolts and provide some good midrange power.
My thoughts were either an F14 on 112+4 or F13 on 112+2 or +4.
My supports mods are as follow:
lid
85mm maf (slightly massaged)
home ported TB
LS6 intake
QTP long tubes & Y (gutted cats)
SLP Loudmouth
HP Tuners

Thanks, that was somewhat helpful, but as you see in my original post I did do a search. I'm really looking for info specific to the cams I listed, F14 on 112+4 vs. F13 on 112+2 or +4.
I'd really like to know the differences in power and power band between these 3 cams and whether or not I'd actually notice the differences.

sounds like you want the F11.

peak-6400-6500

f13 peak +200rpm

f14peak yet another 200rpm.

you need F11. lower dyno number,,,maybe, but more usable power in your rev range which makes you faster. better gas mileage and driveability. i just ordered mine

I know that if I went with the F11 or F13 I would kick myself in the *** later cause I could I of gone with the F14...so theres my vote for you.

I've got an F13 on a 114 lsa and it peaked right around 6300 and I shift around 6600.

I had the f14, with the peak you are looking for, go with the F13.
search for F14 with my name as the poster... I've posted about that cam and other variations plenty of times.

Don't know why he stopped at 6300 but it had pretty much flattened out at that point anyway.

One of these days I'm going to get a pulley and dyno her in cold weather I'm hoping that if I do that I'll hit 410-420rwhp cause it was pretty hot and humid that day.

my friend was trying to convince me to get the F13, but i decided against it. Now i think i should have ordered a custom cam with the duration of the F11 but the lift of an F13. Too late now..i'm sure i'll be happy with the F11. I wanted to mosey around town at under 2krpm..i hope this cam does it for me.

I have an F13 in my 2000 ss and I love it. Great street cam, pulls good througout the rpm range, Im shifting around 6600 also. Dont know about numbers, getting dynod on saturday, and track sunday. But last night I did keep up with 119 mph car proven. Mods are F13, Ls6 intake, ported tb, Lts, pulley

My car is 3700 lb's and traps 121 mph with heads that dont flow but 257 cfm's, I shift at 6600 and my dyno peaks around 6300 with the f13+4 on a 112lsa.
Allan FUtral will tell you that there is maybe 5 hp between the two cams just the sound is better on the f14 and the f13 is tamer for the street. Pick your poison

hmm...shouldnt it peak higher than the F11 on a 112? I guess they both peak around the same area
i found this dyno graph for the F11 in another thread

I loved my F11, I did 401 hp and 395 tq w/ stock heads. Full bolt ons, LS6 intake, X-pipe with bullet mufflers.

I have the F13 112 +2, it peaks around 6100rpm.
If I were you, call Futral and jabber with him - he will direct you in the right direction.
