C5Z, drive it a couple of times a month. Narrowed down my choices to a BTR II/III (dont know which one I want) or a Torquer V4. What would you guys recommend. Plan on getting my heads worked next. Mods in sig. Thanks for the input.

Not a huge difference between the 3, but based on the specs alone I kind of like the V4

im still learning about the cam specs by reading the forum, for my knowledge, why do you like the like the V4 over the others

lcfdvette

Have you spoken to Tooley to see which one he suggests?

You should talk to a cam grinder. Those basic specs only tell part of the story. Lobe profile for instance isn't a listed spec but affects it as well as how long your springs will last. Asking on a forum elicits responses from people that have had maybe at best a couple of cams and I've seen people's tolerances for what's "streetable" be quite varied.

Agree with Svede I would talk with Brian and/or Kip @ Cam Motion.
That said however my selection between the three listed is the
BTR Stage 2, reason being least amount of overlap, mid-upper
220s good intake duration for 5.7. Cathedral heads
typically need 4-6* more exhaust duration
Depending on exhaust port and system efficiency. Stage 3 has huge
(for NA) exhaust split of 11* VR4 has a little short 3* exhaust spit.
The stage 2 will drive better on the street and be easier to tune
Will provide a significant performance increase with your stock
Heads as well as ported or aftermarket.I would also look at the
Cam Motion Titan 4 227*/232* .612"/.595" 113*+4* similar
Numbers, with quality steel for cores and gentle lobes for more
Valvaetrain stability/durability @ high RPM and quieter operation.
Just My .02

I Have a C5Z with the BTR Stage II cam along with TF 215's and a few other things. It has decent grunt down low and spins up pretty nicely. However, it is a Comp cam and the BTR replaced a comp cam that was installed properly with the correct springs and preload, and the lobes took a dump. Now I have another comp cam in a different LS that appears to have wiped lobes. Given my own experience, a cam ground on a Comp core would not be on my list of potential candidates. I learned the hard way but this time I specified that my cam be ground by Cam Motion on one of their cores. It doesn't really cost any more to have someone like Tick spec a custom cam on a Cam Motion core and it only takes a week from the day you order until it's delivered to your door. Tell them what you want out of the cam & let them design it for your specific needs. I'm no expert, but to keep the fun factor of driving your C5Z, I wouldn't go more that 2*-4* overlap and I'd want lobes and lift that afford decent service w/o having to replace valve springs every 10K miles. But that's just my opinion & you know what they say about opinions - they're just like ***holes, everybody has one.

"And they all stink" is the rest of the saying...

Mine is up to 8 degrees of overlap on a manual is perfectly street able and very fun. I would bet auto could take more. My wife thought my old cam with 2 degrees was too lumpy.

I couldn't get my f13 to buck or surge even, didn't matter if it was in 6th at 40 miles per hour or going through a parking lot, that had 7 degrees of overlap. New cam is going to be either an EPS 226/234 or a 226/230 both on a 111 LSA, or the FTI Streetsweeper HT, reading the old cam thread with Jrod and Ed and Pat G opened my eyes to a lot of things.

My old cam was a comp 228/234 588/598 114+4 and it drove great with my t56, I was on the 7k limiter more often than I wanted. It pulled awesome, so I vote btr stage 2

SSEUL8R

I vote for the SSHT, and it has 8 degrees overlap, I could DD my car if I had to. Did the numbers in my sig, 394/390 on a dynapack, and the OP has 243 heads. It could do a lot more in his if he has some supporting mods.

Give us a call. We would be happy to go over your combination and goals and help you select the cam that is best for you. Our number is (512)863-0900

Also, it seems there are still a few that are unaware but all of our cams have been redesigned using softer/more stable lobes and are ground on Callies cam cores.
