Hey Detroitmuscle, did you have to flycut your pistons when running that much lift and 110 lsa? What is your ptv clearance?
i am getting a 235/240 .621/.609 111+1 cam and i'm worried that i'll have to flycut on my ls1.
Thanks!

I did not have to fly cut my pistons, I am running ETP 5.3 heads and GM MLS gaskets and I had at least .100" of clearance.

where can we get more info on these LSL lobe cams?
i have been searching, and must not be looking in the right places.
thanks!!

Currently running a ls2 with honker coldair box, ported t/b with a fast 92mm intake and kooks 1 7/8 lngtubes w/cats B&B exh. making 410rwhp & 403ftq , will be adding patriot 243's harlandsharp rocker arms 1.7 and a comps 238/242 610,604 on a 115 lsa, CAN'T WAIT TO SEE THE RESULTS.

Check out comps website. LSL/LSK/LSR lobes are similiar, I liked the way the LSR lobes looked personally but I am not sure how fond I am of Comps shelf specs. I believe some vendors are beggining to play around with the LSR lobes more and more and should make great power with good flowing heads.

Chris, thanks for the response!
i tried comps site, but didn't really give me details on these lobes. i'll try again.
i was considering a 243/251 or a 239/247 for an ls3 418 stroker.

Here is a list of their N/A cams. Seems like Comp really liked the 16 degree split on a cam that would be directed more towards your app. I would try to stay closer to the 114lsa, as the stroked motors dont always need a tighter seperation. I am sure Pat.G, Predator, or Ed curtis can point you more towards the right direction here.

hey, Chris,

wow! thanks!
i already spoke to Ed Curtis. i like his cams very much, and have had two of them .. the reason for considering any of these ones is as a result of trying to be a little "open minded", just doing research to make a more educated decision. i have seen results on my first choice. now, i am seeing results, and very nice btw, with these lobes.

sent you a pm.

jegten

iTrader: (22)

sorry, i forgot to mention, i am using cathedral port heads.
i was thinking 113+3lsa, or so. your thoughts?
bold faced-that is interesting.

Chris Gage

iTrader: (18)

I dont want to jump off topic here so I shot you a PM.

Sorry OP

jegten

iTrader: (22)

yes, OP, sorry. i got carried away.
but, it was all prompted by your great results. thanks!

New news about my cam i just got, I pulled the trigger on Speed Inc's SI6 cam 235/240 .621/.609 111 lsa and to my surprise i got it and the comp cam card says 235/240 .643/.609 111+1 lsa........ wow that's crazy for a C5 6 speed TEA 5.3L heads isn't it? According to Larry i should be still ok on ptv clearance i guess we'll see. Oh btw, my point of the story is this cam has LSK lobes and the .621/.609 lift has LSR lobes.

I am going to bring this thread back from the dead because I am thinking about putting this in my ls2. First of all 349 with headers is low. A ls2 with long tubes should be about 375rwhp in a m6. So if this gains 79rwhp you should see about 450rwhp and nearly 470rwhp with fast, lt's, cai. I know Iam bench racing here but just estimating and pointing out that ls2's with lt's make more than 349. Has anyone else tried this cam, if so post your results, thanks.

You'll still be fine on ptv but that's not what you ordered. I'd send it back to speed inc and ask for what you paid for. The LSK lobe is violent. It is VERY hard on the springs and I know a few top LS engine builders won't run them ever for anything. They're also very hard to control at high rpms, especially without lightweight parts like titanium valves.

Someone fucked up and ordered or ground the wrong lobe, you should get what you ordered.

this is true, i was running longtubes and a CAI before and i was at 370rwhp

I'm using the original posters cam in my 402 stroker build and should have the results this week. fwiw

mercccc

just got mine tuned yesterday...its a 2000 trans am m6 with a stock l92 bottom end, prc stage 2.5 5.3 heads roughly 11.46:1 compression 235/243 .621/.624 111 cam, pacesetter headers, no cats, magnaflow cat back, unported fast 92 w. nw 92 tbody, moser 12 bolt with 4.10 gears, tsp 100mm maf, and it put down 473 whp and 436 foot pounds on a mustang dyno...working on getting the graph up

Holy crap that's awesome! Especially on a mustang dyno. I got the same cam going in a very similar motor. I got a 1999 TA M6 forged 347, PRC Stage 1 LS6 head milled to 60cc, Pacesetter headers, no cats, flowmaster merge with cutout, hooker catback, hand ported 90/90, and Moser 9inch 3.89 gears. I hope I get the same results with a slightly smaller motor. Would love to see the graph whenever you can get it posted up.

mercccc

this is the graph before the 100mm maf, 104mm lid, and the slowhawk tune..should have the new one up soon tho

I have this cam and it put down 468rwhp and 439rwtq with the mods in my sig. Thats using the stock ls2 intake and throttle body also.fwiw

This Cam is impressive imho

mercccc

i like the cam alot also, our power looks to be very close. thats pretty impresive with stock ls2 intake and tbody..i did trap close to 123 untuned without the maf and new lid last week in a 3700 pound car in 94 degree and very humid weather
