Here is what I am considering.
I am picking up a low mile, unmolested engine out of an 01 SS.
I don't know if I am going to have the budget to get the heads ported by a local guy or not. So this may be a cam only decision for now.
My car has a Yank SS3600, 3.73's, ASP, Headers, etc and previously had a Futral FMS-4 and ran great in the internally stock 98 engine.
The specs on the FMS-4 are

Here are some of the cams I am considering.

Leaning towards this one.
Then these 2 from Vengeance Racing.

 

All very close choices. You didn't say m6 or a4 but people put too much in that anyway, A good tune will make a low LSA cam run just fine with an a4 with adequate stall. I like the VRX4 for this setup. Your rodbolts can handle the upper rpm and at lower rpm that LSA will have some bottom.

My tq. at the wheels exceeds +350ftlbs. from 3400-6300. Keep in mind that is more than the stocker nade at the FLYWHEEL through that range so a well thought cam can be better all over and not really give anything up.

 

It's an A4, hence the Yank SS3600

nice avatar

 

Check out the Thunder Racing 230/224 .575/.563 111lsa. After my tune, the car drives almost like stock and has some bitchin' low end power!

Mods are in sig.

 

I don't need a ton of low end power considering I have a 3,600 stall. When flash the converter id goes to 3800-4k

 

VRX4 is an awsome cam I have a custom grind that is almost identical but I added 2 degrees of timing to it cam specs in sig. I Put down 388/373 with stock heads, stock intake, stock TB, no UD pulley. 2004 M6 GTO Daily Driver. Great strret manners excellent midrange power. Id like to go for Goal of 400 wheel with stock heads when I port my intake/or buy Fast/Street Warrior add my PP 85mmTB and get a ud pulley and have my tune tweaked a lil bit. Best of luck with your setup

Heres my Dyno Chart With stock Clutch and Stock TB

 

Wow, nice numbers!

 

Thanks, I freakin' LOVE this cam!

 

in all honesty...

the 3 cams you listed as "upgrading to" are not big enough to warrent the hassle and retune.

go >230 or don't bother


spend the money you're planning to use for the cam...and port the heads.

you'll get significantly more power from budget ported heads on that old cam than you will just swapping the cam on stock heads.

 

This is a good point. The old cam is in my stock engine that developed a knock. When I drop it out, I will check the cam. If it is in good condition I will re-use it. I was just considering these in case the cam is damaged.
I put down 374 with the stock 98 heads. With a set of ported 241 heads, it should get me close to the 400 mark.
Wouldn't I need a re tune though with ported heads?

 

It is still nice have to have bottom so your tranny is not unlocking and downshifting all the time when you DD

Everybody thinks if you have have a stall bottom end makes no difference but that is pretty much on a strip only car IMHO.......

 

yes you'll need a retune after heads

 

Ive had the Futral F-11 and liked the cam alot. It had good manners and went 11.67 @121 with full weight and stock ported heads. It also went 10.66 @133.5 on around 200 shot.

Watch out for big cams and high peak dyno numbers. They usually dont perform at the track without 5000 stalls and 4.30 plus gears.
