I'm looking for a cam that will get me close to 400 whp with just a cam and bolts ons. my motor is a stock 99 ls1 with ls6 intake manifold and long tubes. will have no accessories and will be a daily driver. so I'm looking for a good street cam. and its on a 6 speed Manuel trans.

IMO for a DD, something in the high 220/23x duration on a 112 LSA. No need for a donkey dick cam. Max IMO I would be looking at is 230/236.

My VRx4 which is 228/230 @112 Made 385 RWHP in a 6 speed but I have a 3" Steel DS and a Moser 12 bolt and a HEAVY Tru Crap Diff. I wager if I tossed in a stock Aluminum/10 bolt combo, I would be right @ 400 RWHP. I have a lid, dynatech headers w/ Catted Y pipe matted to a Corsa Exhaust. The car has excellent manners, phenominal under curve power which is a blast to drive on the street. Makes over 350 RWTQ @ 3k which is better then most D.D. cams like MSx, TRex etc etc

Definitly possible. Typical Heads/cam F-bodys make around 435 with supporting mods so 400 cam only shouldnt be too hard. My best advice would be to conact Ed at Flowtech. He will point you in the right direction. Tell him what your goals are and that you plan on DD'ing the car.

+1.
However, Based on your current mods, and if you plan on keeping the ls6 manifold and stock heads, you might want to look into a reverse split cam.

If I got another cam, to be honest I would check with EPS, some of their grinds have been putting out sick #'s I don't have faith in reverse split cams. IF I wanted Max effort stock cube/head LS1 the TRex is a proven cam time and time again.

I had a Fast 90/90 (ported) on this car but performance was hurting (should have left it UN ported by Vengence). Either I will do a different H/C on this car and pray the bottom end never grenades (46k on the clock), or toss a 100-150 shot on and just have fun. We will see.

A 228/232 113lsa cam should just make it to 400rwhp with good bolt-ons and have great drivability too but it is mostly the tune that will make the car great on the street. Shouldn't have to rev to the moon either, maybe 6400rpm redline. 224/224 cams like the tr224, 224R are around 375rwhp so you would need to go bigger than that at least.

Some of the cams ^^^^^^^ they talk about should get you thier if you have a good tune or close to it.

Lunati has a relatively new line out for LS engines. They seem to take forever to get info out to the masses about new things, don't know if it's for good, bad, or indifferent reasons.

http://www.lunatipower.com/Media/Doc...0LS%20Cams.pdf

I picked this one with help from the tech department with matched springs and pushrods: 2200 - 6800 CAMSHAFT, GM LS VHRX278-12X 278/282 adv. 227/231 @.050 .651/.651 112/108 LSA/ICL

I haven't found anyone running any one of these yet, but I'm hoping to fire mine in the next few weeks.

My Torquer V2 made 445rwhp/395rwtq with Heads and FAST90...I'm sure a slightly larger cam would do the trick. I've heard great things about the MS4. I would have gotten it if I didn't get a good deal on the milled heads.

I made 417rwhp thru a m6 n 10bolt w my tsp 228r stock heads w 42lb injectors n fast90/90 car had awesome street matters n won't have even know it was cammed other then hearing the idle. I just swapped it out for the brute speed blower cam bc I'm going w a procharger, but there r a couple guys on hear that run this blower cam n/a n picked up over 70whp from it

BlackScreaminMachine

Typical Blower Cam grinds will make less power then it's N/A Equivelent @ a given rpm range but like said would make good power. 70 HP is a major jump, but then again cams like a out of the box 02+ Z06 cam is a really decent grind that works well with a FI set up.

But Ultimately, you need to look at under curve power as the powerband is often shifted forward.

Im posting this as I have a few who put some blower spec'ed grinds into motors and really suffered until that blower set up was installed. So that was interesting to me.

I had the ms3 cam in my dd. I was on stock ported heads and intake with all the supporting mods and I made 408rwhp with 380 rwtq through a m6. Oh by the way that was on a mail order tune from texas speed. I'm sure the car would have made close to 430 if it would have been dyno tuned. I loved this cam. If your not familer with the ms3 its 602/609 lift with 238/242 for duration mine was 112 lsa.

I dont remember who it was that did it but I do rember seeing dyno graphs, n yes there r some that do swap in the blower cam
before they install the kit n loose power, maybe who did it will chime in. If I didn't already have my kit i would retune it n post my results but I'm not in that boat right now

a Better question would also be what is a max lift that can be accomplished with the stock bottom end and not having to flycut the pistons for valve reliefs? while having these crazy .6++ lifts not really looking to fly cut or end up bending up valves

id say go with a custom eps cam call Geoff. his cams have been relatively small but been making alot of power. or the ms3/ms4 great proven results from them that are over 400rwhp.

Dont know about a MS4 for a daily driver. Read on here that it can wear out the springs really fast - Magic Stick V.4 239/242, .649"/.609. Lot of lift and you will need some really good springs - PRC dual valve springs would work. Plus on a stock setup you will have to flycut the pistons.

JustAnotherLS2

OP, looks like you got more than enough input. Should be able to make your desicion now without losing any sleep.

Duration and ICL really determine PTV since max lift occurs near BDC.

The MS cams and Trex are about as big as you go with an unmolested motor but they are not even close to DD friendly w/o supporting mods like gears/stall IMO.....

Like stated a high 220-low 230 cam can be DD friendly with a good tune. I could have easily DD my old 230/234 cam in my 346.

you do not need to flycut the pistons with the ms4 and stock heads. my friend just did the combo and did not have to flycut and there are many people on tech that did not have to flycut with stock heads
