Hey guys, I�ve got an �02 ws6 with 31k on the clock. current mods are lid, slp lm, yank ss3800, pba shift kit. I will be installing qtp headers and non catted y-pipe. I ran into a unique opportunity at work recently while I was working on a chiller at engine power components they make cams for snowmobiles to huge yachts and everything in-between. Well in that in-between they supply cams to comp and possibly many others ( the machine operator specifically mentioned comp) so i can get a custom cam for next to nothing from them. I plan on staying with stock heads with upgraded springs and pushrods. This is a street car that will occasionally see the track. I know there are a ton of options out there so im just looking for some suggestions. Thanks!

 

Something in the 228 duration range seems to be a good spec for what you are looking for. Good street manners and not so abusive on the springs.

 

Along those lines keep lift at .600 or less. .550 works for a lot of the milder cams and works well with LS2/3/6 beehive springs.

 

Yeah seen a couple of comps cams that were in that range. Xr281hr 228/230 .571/.573 112lsa and xer273hr 224/230 .581/.588 114lsa but I’m assuming i can give them any set of specs to grind so Is there anything you would tweek on those cams that might better suit my mods?

 

Something similar to the Titan 4 or BTR stage2 would work seemingly work well with that setup. Much bigger and I would assume the stock heads would become serious limiting factors.

 

This cam isn't mentioned as often around here anymore, but the Ed Curtis streetsweeper HT is a perfect cam for a mild stalled streetcar. Had that cam with a 3600 stall and it drove great and made great power for being a smaller cam by most standards nowadays.

 

227/232
600/600
113+4

 

Thanks for the suggestions. Yeah I do remember hearing about that ss ht cam a few years back. I ran the numbers on it and it has 8* overlap. Was it tough to tune? Valvetrain hold up pretty good? Numbers are similar to pooterSS suggestion, on his the exhaust open, exhaust center line and overlap are the major differences. Ss ht ex open 47* ex cl 111* intake open 3* intake cl 111* 8* overlap. PooterSS ex open 52* ex cl 116* intake open 4* intake cl 110* and overlap 3* I’m not sure how much subtle changes to either cam will change how it would preform. So if that 8* overlap is a little fussy to tune I could bump the lsa to 112 and get 6*. And if I wanted more lope from pooterSS I could bump the lsa to 112 +4 and get 5* overlap. I would prefer to make power down low and not have to spin it over much 6300ish.

 

FWIW - The 02's have good bottom ends with good rod bolts. They are bullet proof to spin to 7,000 rpm with good valve train. Power peak at 6,300 rpm and shift ay 6,800 rpm will work very well.

 

Fantastic all around performer

 

Interesting, I didn’t know that about ‘02’s. I guess I’ll let her eat a few more thousand rpm then. As far as valvetrain I was looking at some pac 1219x beehives rated for .625 lift or pac 1221 duals rated for .650. Thoughts on those springs? I’m not too worried if the duals are a little noisier or cost a little more, so if it would be beneficial to me to go with duals and not be “too much spring” I’m all for it. Thanks.

 

The SSHT was cake to tune. The 8* of overlap shouldn't be hard for any tuner who knows what they're doing. The valvetrain held up great. I used Lunati dual springs that came with the cam from Flowtech.

Go with the dual springs for added insurance.

 

Based on what I've read the rod bolts were upgraded in late 99 and then again around 01.

 

I have a high mileage later ls1 swapped into my 94z, and i abuse it badly with .660 btr spring kit. I shift as high as 7600rpm sometimes because i have a blower cam with large split and 114lsa, and (i think) it has no advance ground in. I didn't get a cam card with it at the time so i installed it straight up just in case, wasn't going to pull heads and check for p/v clearance. I threw it together in a day. Not how you should do it. I have 6000+ miles on it since the cam install and running it in my car, lots of rpm and WOT passes, it won't die.

In my first LS car years ago, i had a 230/230 591/591 112 lsa (Futral Motorsports F12 cam), that was a perfect street/strip camshaft. And only needed 7200rpm shifts. Got me in the high 11's n/a in a 3700lb sedan without much effort.

From memory i think that cam had 4 degrees advance ground in, might have been 2 degrees, i've forgotten.

Anything around the 226-234 duration, around 600 lift, and 112+4 will be good. Any larger than that, i'd want a higher CR, milled heads, and get's into needing valve reliefs territory.

 

Thanks launch. Were both cars running stock heads? From what I’ve gathered 7.4” pushrods should work for me. We will measure but I’d like to have the right parts in hand because I’ll be doing it at a friends shop so I don’t want to hang up a bay for more than a day if I can help it.

 

My previous car with the futral f12 cam, first it was stock heads, went 11's cam only. Then i fitted cnc'd big valve 5.3 heads, picked up near 4 tenths and 6mph at the track. Went 11.6@119.xx mph, repeated it 3 times that day and i never returned to the track to sort out the lack of traction and better the combination. So yeah that F12 cam worked very well both stock heads and with ported heads. Pushrod length with my Futral F12 cam were 7.350" pushrods.

 

Hey guys, finally getting back around to this. The cam im looking to get made is a 226/228 .598/.607 112+2 lsa. Any thoughts/ suggestions will be helpful. Thanks

 

Cam Motion, TSP, BTR and Summit all have similar cams on the shelf. I don't see any reason for a custom ground cam with those exact specs.

 

Im getting the cam made because i can get it for pretty much the cost of the steel That will be used. Hell, im thinking of getting a more aggressive one made also incase i do heads down the road...

 

Cams are such a tough thing to suggest, but if I were looking for a cam for stock heads, I'd be looking for the one that makes the best hp and tq. usually there are a few that are super popular for a reason, because they flat out work. FTI Streetsweeper HT is a winner from probably the best cam designer, Ed Curtis..it's been mentioned earlier in this thread. It's a proven cam with a solid reputation for delivering huge torque and hp. Another solid grind is Ticks SNS torquemax Stage 2. My buddy runs that one and has gone a best of 11.25, it a cam only bolt on car with a 9", 4.10s, and a 4500 stall...yet he drives it absolutely everywhere with no issues. it sounds like a monster but drives beautifully!
