Getting a Cam/header/fast92 intake/variam/ ls7 clutch c5z. Its got a bullshit BTR stage 2. That's going to have to go away asap lol This thing is going to get roll raced . so whats everyones ideas.. Who should I go through for a cam?. I don't want to yank the heads and get them ported yet. c5z's are lighter than fbodys and are way better in the air.. So not sure what I should go with.

I'd reconsidering the LS7 Clutch, there are better clutches to choose from. The McCloud RXT Twin Disc is pretty fantastic all around.

The BTR LS1/2 Stage II Cam 227/234 .614"/.576" 113+2 is a pretty decent cam.

This seems like a good Donkey Dick cam for your application from Flow Tech Induction : It has a out 22 degrees of negative overlap.

The infamous "HELLION" LSx Hydraulic Roller Camshaft

SPECS: 244* - 248* - 112* - .631" - .631"

This BAD BOY has massive horsepower up top and more "under the curve power" than any camshaft in this range. Very stable lobe design when coupled to the correct peripherals and will not destroy your valvetrain. PAC Racing valve springs and heavy wall push rods highly recommended. This extremely popular FTI camshaft is a proven horsepower maker that is used in many stock block "cam only" style builds. Be prepared for knocking down the competition regularly with this stick.

The RESULTS don't lie, only your competition does when they're beat!

Customer results:
Corvette C5 - 347 forged shortblock - AFR 205 heads - LG headers - over 500 RWHP - ten second time slip
2005 GTO - 364 stock shortblock - ETP 225 Heads - Kooks Headers - FAST 92 - 513 RWHP

Piston to valve clearance must be verified with this profile!

Try a CM LLSR in the 234/240-ish range

The BTR2 is fine for what you are doing...want more power you need more cubes or forced induction. For roll racing I'd hook up a 200 shot and have it kick in gradually at WOT. Could even hide it with some thought. Too much cam will make you slower without proper mods. 4500 stall in an auto or 456+ m6 gears and a much more aggressive transmission gearing ratio, AFR heads and a diet, then those 240 cams would interest you. Even then the nitrous and smaller cam will be better.

We have a very aggressive 233/241 that is all about top end power. Its a monster at idle and turns on like a light switch above 3k. Pulls hard to 6800 with the fast92/102.

Youll want to measure, but it should reuse the 7.400 prs and will reuse the dual btr springs also. Cam is $389.

MS4, from me 250! LOL

Really though, I would think you would have this figured out already. Just get a good 300HP nitrous cam and of course, the supportig 300 shot.

why over cam the C5Z? Get rid of the LS7 clutch for starters.

On a side note, what happened to the 416 powered F-bomb?

Like already mentioned I'd get rid of that heavy LS7 clutch for starters. The BTR stage 2 cam is a great cam but if you want more of a top-end monster for roll racing I like Flowtech Induction's (Ed Curtis) Street Sweeper 236/240 .631/.610 111. I'd personally keep the cam you have since it's a real nice street cam and add some juice but if you wanna stay cam-only the Street Streeper is a solid consideration.

I have an RXT in mt Camaro. Love it. Never said I wanted a donkey dick cam. I just don't like BTR shelf cams. Never seen one perform good. This thing loses power fast lol I hate it TBH every car ive installed one in I hated it lol

FYI.......the C5Z weighs 3080 pounds
the MN12 trans has a 2.97 low gear....not too bad even with a 3.42 rear
200 or more juice will usually close the ring gaps and eventually break off the hyper pistons
and lastly the LLSR of 234-240 will "act" like a 229/235 hydraulic cam but be a bit more stable in the higher rpms

I was under the impression that if a BTR2 was too small for him, that what he was looking for would turn at an rpm that wouldnt be safe on the stock bottom end (for hard daily use) for very long anyways. If he isnt interested in making it strong as well as fast, then just leave it as is...What does it pull too? 6600ish? That would be perfect for a stock bottom end. Wouldn't go higher personally. Besides any more cam then that you will start to get driveablility issues. If you really want to be competitive, for example roll race GTRs and new Vettes, you will have a hard time winning with a stock cube street friendly ls1 on motor anyways, forced induction would need to be in your future. Unfortunately these engines arent at the top of the food chain any longer. Shoot, I just read about how you can buy a 700hp Roush mustang for about 19k over base price. FI is the way to go it seems nowadays, to stay competitive.

Btr stg 2 runs out at about 6200.
A llsr would cost quite a bit more vs a reg hyd roller to give him the top end screamer he wants.

Bspeck82

Indeed it will, if he wants to go that route then by all means please do. I'm interested to see the results. In just worried he will overcam and it will feel like it pulls harder up top, but only because he killed it down low. Happens too often.

For roll racing that is what you want. a firecracker.

Gotcha, happy to hear your not a Donkey Dick cam fan.

Bigger than 227 intake duration can start to lose torque in the lower rpm. The spec's of ~ 227/235 ​​​​ is about as big as I'd want in a daily driver.

Since the FTI HELLION is too extreme, I suggest checking out some of the smaller FTI cam's. A 231/236 Sinister cam from Hawk's Motorsports might work pretty well. I think Ed Curtis of FTI works pretty close with Hawk's on their cam specs and selection.

going with a TX Speed 223/226 .605 .598 111 LSA Lonnie specd it. its on decently aggressive lobes so well see how she does.

I ran a vindicator on my ls2 powered C5Z06. Love it and had tons of top end power. A friend of mine used the same cam in a 5.7 LS1 Camaro and same thing, top end power like crazy. In the C5 I had pleanty bottom end power.
