COnsidering these cams, input? 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

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

Vengeance Racing VRX3 Camshaft
226/228 .585/.588 114 LSA. Our most popular Street Camshaft. 1700-6700 Power Band. Excellent Street Manners. Lots of "Power Under the Curve". Choppy idle. Computer tuning is required for best results. We suggest Comp 928 Valvesprings

Vengeance Racing VRX4 Camshaft
228/230 .588/.592 112 LSA. 1900-6700 RPM Power Band. Serious mid range and peak power. Excellent choice for street applications. Computer Tuning is required. We suggest Comp 928 or Dual Gold Springs be used with this camshaft.

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.

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

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.

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