So heres the deal buddy of mine wants to do a cam on a 98Z with 131K on it.
the engine has been very well maintained and runs great but ill be getting a new LS6 oil pump and new timing set. Were lookin to rev the motor no higher then 6400 and stall no higher then say around 3K. Right now the car has 3.42 gears full exhaust including LT's an SLP lid with bellows and a ported TB. He will probably be using the stock LS1 intake for the time being and stock pully. Already have a set of new 918 springs sitting around. His goal is a nice choppy idle kinda similar to my MS3 cam if possable just slightly less, with some decent torque and mid range and upper end power. We were thinkin about somthing similar to a 224 cam but the idle is pretty weak on those from what I've heard so open for suggestions. The car will also be getting a lower stat and a full dyno tune of course once we pick put a cam. Remember catch is the carstill has over 130K on it so cant go crazy here...

If he wants a less rough idle than your's just tell him to get the ms3 on a 114 LSA.

Problem solved.

the cam's idle is that important?



get a 224 and put it on a 110+4 lsa. you got your lope, use of a 3k stall, and your basically stock shiftpoints.

done.

what about somthing like 226-228 581-585 110+4. Thats a number we were thinkin about.

about an MS3 with a 114 LSA thats way to much for a motor with that many miles and besides not a good idea to spin any 98 to 6800+ now is it.

Just be sure to keep an eye on oil level. Oil starvation is going to be the number 1 killer for his motor. Higher average RPM and old piston rings are going to mean keeping a close eye on oil level to prevent spinning a bearing.

I don't think you'd need to spin the MS3 that high...I'm sure shifting before 6500* will do just fine. If he's worried, get some rod bolts and go for it.

I agree with this advice. Instead of installing a known handicap, get some better rodbolts and go for it!

"Go big or go home" comes to mind.

Was that sarcastic or no? Hard to tell on the internet...

Either way, what I posted above is just how I think. My 160k mile m6 z/28 did a 13.4 on street tires with just a lid on it. The car ran like a raped ape for the amount of miles on it. I had a th350 built and planned on running a 4000 stall and a 150 shot...And you know what? I bet the car would have absolutely loved it.

Miles shouldn't scare you if you know the maintence record. If it's been taken care of and maintained on time, you shouldn't have to worry. LS1s are remarkable motors as far as power delivery and reliability.

I say go for the MS3. I've seen that cam work. Double springs, hardened pushrods, and new retainers...Get the best dyno tune possible and your buddy will wonder why he ever thought about going with something else. PM "Matt D."...He ran the cam and can tell you all about it from first-hand experience. He drove that car everywhere and ran some impressive numbers for what it was.

It was genuine. Can't wait 'till I pull my motor for rings, bearings, and rod bolts. You really did make a good point.

Oh ok...That's what I figured but you can never be too sure.

It's like the Ronco commercial...Make a call to ARP...Then put em in and "Set it and forget it". Or in this case, torque it and forget it.

Yeah but the problem is he is working on a $1900 budget and The MS3 needs to be spun to 6700+ to make the most of it I would know I take mine to 6800 and if I had an upgraded bottom end I would go to 7K+ if he wants to keep a shif point of 6400 or lower the MS3 is a bad choice havent you guys ever seen a dyno graph for this cam?

have you thought about a torquer cam? Peaks lower than the magic stick, more lope than a 224 and you dont need to spin the motor as high.

TR224 on a 112lsa.better power under the curve,and you won't have to rev it to the moon.and if he wants a choppy idle,just set the idle lower...

Can anybody tell me more about this torquer cam? Anyone that has it?

You can find the specs and information about this cam from a sponsor called Texas Speed and Performance in far right hand corner--------------------->

There is a Torquer 1, 2, and 3 cam, check them all out.

I'll tell you more when I get it installed. I just got it in the mail from TSP two days ago. Was leaning toward a 228r for driveability but I saw many torquer2 cams out there that drive just fine. It"s got the 232/234 .595/.588 112 LSA. 110LSA may shake the crap outta ya at the stop light if used for a daily driver. Also, idle at winter time could be an issue if you live in a colder climate.
