I am planning on upgrading to the PRC LS6 stage one heads from Texas speed.
I have been considering 3 of their cams so far:
TSP 228R 228/228 .588/.588 1600-6300 RPM Power Band 112 lsa
233/239 233/239, .595"/.603" 1900-6500 RPM Power Band
Torquer v.2 232/234 .595/.598 1800-6400 RPM Power Band

The car : 99 Corvette, 6 speed, stock 3.42 rear. LS6 manifold, Vararam, longtube headers and Corsa pace car mufflers. ECS tune. So far ran a best of 12.61 before the headers and tune. 30k miles on it.

Not a daily driver.
Don’t care about idle sound – or idle quality as long as it doesn’t keep stalling.

None of my choices are what I would consider a really “big” cam; I just want the most torque and the flattest curve. These cams seem so similar; I am now leaning towards the Torquer. I am trying to avoid the dreaded “I should have went with a bigger cam syndrome”

Any opinions and thoughts would be appreciated, thanks!

When I ran a TV2 and put PRC Stage 1 243s on the car it picked up 50 RWHP. I never had any idleing or surge problems even with the AC on. I had the cam that was ground on a 111. It had a lite chop sound to it at idle.

I have been looking at these same cams. I think i am going with the Torquer v.2

I would have expected a bit more than 50 rwhp from a heads and cam package.

Stock displacement right?

How high do you plan on revving it? The power bands posted for those cams seem a little off on the high end, I think they could be revved a few hundred RPM more than that.

look in the dyno section for more results on those cams.

Stock displacement, I would like to keep the revs below 6500. Still has the stock rod bolts.

Out of those, I honestly would run the 233/239. I wish i would have went with that cam the first place. Its a good size cam, and probably the biggest i would run in a daily driver, fun street car. I have a 230/227 and my cam is so civil. I have thought about upping my cam to that 233/239, but for me i dont think ill gain a whole lot.

I have the TV2 and it revs to 6800 with stock bolts.

In that case you should shoot for peak power around 62-6300RPM. The 228R is the closest to that out of those three.

Someone suggested looking in the dyno section. That is a pretty good suggestion and you can sort of see how these compare not only in peak but more importantly in where they make power.

All in all if you go with sort of mainstream ramps you will probably find that you might be best suited with intake duration at .050 in the low-mid 220s... like the ubiquitous TR224, or the TSP 224R (or even EPS 222/226).

does it HAVE to be a TSP cam?

No, those are just the choices I looked at so far.

you get a better deal buying a head/cam pkg from TSP.also look at a EPS cam,great power with less duration.
