Camshaft?
IM looking to put a cam in my 98 vette 6speed. The only mods I am going to have is full exhaust header back, cold air, tune and the cam its self. Im looking at Texas Speeds TSUNAMI But for my application they recommend the TORQUER V.3. Any feed back would be great.

Be sure and take their recommendation seriously. If you discussed your wants and what your set-up is why would you question their advise. They have been doing this for quite awhile with success!

Cam manufacturers do A LOT and they do tend to recommend what makes YOU HAPPY!
Texas Speed will do you right and stand by their work.
I do my own work and am not a newbie to building engines. I really loved the customer service and talked with the guys at Sales and in the shop so I'm very confident they knew their business!

In my humble opinion, the torquer V3 may be too much cam for a stock engine with just headers. The huge lift (.643!) will require a really serious complete valvetrain upgrade ($$$$), and the lift/duration specs will simply overpower the stock heads' ability to flow. Will this cam even install in a stock configuration without hitting the pistons?
A much smaller cam, say 224 duration, .560 lift, would probably perform much better under 6000 RPM, and not have all the associated hassles and cost of the V3.
But, I'm certainly no expert like the guys who do it for a living.
Maybe you could ask to see some dyno results of the V3 - then see if they have any data with stock intake/stock heads engines with this cam. I suspect most will be highly modified motors.

I'd keep the lift under .600 I think the Torquer 3 has intake lift of .643. Which might neccessitate checking and possibly changing the valve springs every couple or few years. I believe the Torquer 2 has lift under .600 as well as the 228R cam which might be better if you don't want to think about occasional valve spring checking and maintanence.

Those 98 heads don't flow very well, and will really limit the hp you make.
Depending on the rest of the cam specs, you might have to fly-cut your pistons for clearence (more $$)
You'll hear different opinions, but if you want a FUN car with good low end torque and hp, go with the 224-228 range and keep the lift under 600
Just my .02

I just did H/C on my 98. TSP -233/239 - 112 LSA - .595/.602
This cam has plenty of lope. i have auto and have to run a 3200 stall.
If no head change I agree with Blow Torch.

so even going above a .580 - .590 cam lift wont help much.
224-228 581/ 588 on a 113

Go with the torquer 2 232/234 .595/ .598 on a 112 lsa. I have the same car and set up as you, i was recommended this cam for my car. I'd like to see what numbers you put down after your install. Good luck!

Was just going to say this, the V.3 seems to big for your set up and those heads just suck. If you can get a set of LS6's ported get um but if not no biggie just plan to upgrade down the road and get a lot more power. As for cam the V.2 is a solid choice a lot of F-Body just run that cam and love it. I would personally get a custom grind as they can spec it exactly to your mods and make the most power throughout the curve.

It is my understanding that stock LS1 heads do not flow much above .575 lift so a cam with .643 lift would not produce the H.P that you would expect.
As others have mentioned there are better choices including the V2 or 228r or even smaller.
