alot of you guys rave about the FMS cams

so I checked out some of the #'s yall were getting and was thinking of ordering one of theirs now

Here is the setup I'll have...
04' GTO A4, TCI 3000 stall, and stock 3.43 gears

I was wondering if I should snag a FM12-112 or FM13-112

Do I have enough gearing for these?

Will the 112 idle rougher than the 114 lsa's?

Will it drive nicely?

thanks in advance, i'm sure it's been covered but I appreciate any help

Yep the 112 will idle rougher than 114, but it will be more fun when you put your foot in it. The rest of your questions are largely subjective, i.e. vary according to a persons tastes. IMO it would be fine with your setup and drive nicely, but not as nicely as before. My guess is you will probably get used to the difference and enjoy the improved top end power. Aftermarket cams are for people that like to use the full amount of power the engine will develop; if you never do that you will hate it. But since you are on this forum, I think you are the first type of person.

I forgot your name, but this is Danny (ZYouL8R) from TRS.

Either cam will work fine for you. I have a slightly smaller cam w/ a 4400 stall and 3.23 gears. The 112 will have a little more of a lope to it and may be a slight more pain in the *** to get to idle at times but it's no big deal, it's all in the tuning. Lope is more a function of a cam's overlap, which LSA is a factor of.

I would use FM11 instead

you will sound fast with a bigger cam but you will be faster with a smaller one.I'd stay away from anything over a 224.

I have a Futral 221/221 114 with a Yank 2800 in my GTO. Most will call it a wussy
setup, but I think it drives better than stock. Good for the city if that's where you
drive a lot.

Are you being serious? Dyno results certainly don't agree with that view. My old cam was a TR224, and 224 cams dyno an average of 370 rwhp. With my present cam and mildly home ported heads I'm at 430 rwhp. Both setups are with the same set of headers and basically same everything else.

fm13 just had a buddy of mine go from the 11 to the 13 and he claims its a night and day differance

I'm gonna have to agree w/Cal here, unless you're racing to the 60', the bigger cams are typically better down the 1/8 and 1320, unless you are really well setup.
