Cam guru's.. a lil help please

Alright guys, my friend and I have made a deal that we are both going to do intake/cam/exhaust, by this spring.
The intake we have decided to go with is the LS6, just because it seems the most fiscally prudent. The headers, he is supposed to look up, so I'm not sure yet, my job is to find us both cams.
His car is a 99 SS, convertible, he is more into the show then myself, the car has 20's, and a cat back. He wants a streetable cam, and doesnt want to lose driveability. Mine's also a 99, but a WS6, hard top, both cars are T56, but I don't mind losing a little streetability for more power uptop, as I'll end up doing rear end and head work next winter. My car also have a ZEX wet kit with remote bottle opener.

So basically I need to find him a cam that will wake up his car a bit, considering the other mods; a cat back, intake, and headers, and do the same for mine, but take into account that I expect to go with aftermarket heads and steeper gears in the long run.
So any suggestions would be awesome? We will be doing these swaps ourselves... so any hints would also be appreciated.

Oh and another thing, I've been looking at the F13 and F14 cams, for these two cars, and was wondering if anyone has run the high lift versions? What kinda power and streetability difference are we talking.
For those who don't know what I'm talking about:
F13 is; 230"/232" .595"/.585" 112LSA, the high lift is 230"/232" .642"/.612" 112LSA
F14: 230"/232" .595"/.585" 114LSA and the high lift is : 230"/232" .642"/.612" 114LSA

more agressive lobes = more valvetrain wear.

The F13 is probably the best all around LS1 grind available for stock cubes. Just enough duration to make it run hard while having awesome street manners and great drivability without having to rev the **** out of the motor or lose a ton of bottom end power. I'd recommend getting either one you choose as it comes ground on a 112 +4.

The highlift series is a great "cam-only" cam. You might have PTV clearance problems in the future with it if you change or mill your heads without flycutting your stock pistons.

What kinda valve train goodies would you recommend to go with that F13? Springs, retainers etc, etc?

A good dual spring kit like patriot or PRC. Get the Xtreme springs if you go high lift, hardened pushrods in the proper length, LS2 timing chain, and a ported oil pump.

Judging by the specs youhave up there I'd say F-13 for the tighter LSA.

BUT, your F-14 specs are wrong. You posted F13 specs twice with the 2 different LSA options.

FMS-F14-112 FMS Custom Grind Camshaft - 232"/234" .598"/.598" 112LSA - aggressive profile with a 2600-7000 RPM range, rough idle $399.00
FMS-F14-112-HIGHLIFT
New Item! FMS Custom Grind Camshaft - 232"/234" .646"/.612" 112LSA - aggressive profile with a 2600-7000 RPM range, rough idle

FMS-F14-114 FMS Custom Grind Camshaft - 232"/234" .598"/.598" 114LSA - aggressive profile with a 2600-7000 RPM range, rough idle $399.00
FMS-F14-114-HIGHLIFT
New Item! FMS Custom Grind Camshaft - 232"/234" .646"/.612" 114LSA - aggressive profile with a 2600-7000 RPM range, rough idle


2* of duration isn't much. I would think both would make near the same peak power w/the 14 edging the 13 out, but the 13 will peak a little earlier than the 14.

The F-13 and F-14 can come any way, either 114 or 112 on whatever ICL you want. It's ground by Cam Motion, so Allan can order it however you want.

My F-15 was 112 +2.

I took Mike's suggestion on the F13. Its an awesome cam. It sounds close to stock idling, and doesnt take any hitting the throttle to idle. As far as power goes, once you hit about 2800 rpm, hold on. I like it, but granted I only drove it like 50 miles before i spun a rod bearing.

The F-13 is a 230/232 and the F-14 is a 232/234. Both are great cams and both make great power. The F-14 has a little more noticeable lope and makes power a little higher than the F-13 due to increased duration. It also makes around 7-8 more rwhp on average than the F-13, but most people use the F-13 since it's proven, extremely drivable, and makes power lower.

My buddy made 423rwhp cam-only with his F-14 in a 2001 Z06, then added some box-stock Dart 205s (I would have gone with the 225s) and made a little over 450rwhp all through the stock LS6 intake manifold.

Either cam is a solid choice... The F-14 is slightly larger.

So what does the F13 do to the power curve? Do you lose anything on the bottom? If so, how much and where does it catch back up? And how high up in the rpm does it move the peak hp to?

I really like the sounds of this cam, but this is going in a daily driver that has yet to see a drag strip and probably never will. It only does autox duty a few times a year.

Nice looking curve there! I wonder what it would do with a 10 bolt...

It shifts the powerband upwards like any other aftermarket cam does.

I've seen the F13 peak around 6000 rpm and carry it to around 6400.
