So I'm looking to perches a new cam for my vette. I'm thinking I want something with lift around .570 and LSA around 112. I mainly drive on the street and some times hit the track. Any recommendations?

 

Id concern myself with the duration over the lift. The duration will determine the cams operating range and where you make power. By track do you mean the drag strip, or circle track?
For drag and a daily driver, low and mid range power is where you want your cam. something in the 220's intake and exhaust will be a great upgrade across the board and maintain low end characteristics. Dont let the big sexy numbers of a 230-240 cam make your decision. You will have a fast top speed, but be slow off the line and acceleration; where it counts most for a daily driver and drag car.

Check out Texas speed. They have a great selection and explanation of cams. The 224/228r or 228/228r cam will probably be of interest to you. They come in the 112* LSA as well as others. These will be very streetable too with the 228r being borderline, but doable.

 

You could always go with a custom grind, that's what I did the second time around. Ed Curtis at FTI did mine. What you do is pay for the cam, then he sends you a couple pages of info to fill out, motor specs, exhaust, weight, suspension, tires used, transmission, gearing, what kind of driving you'll be doing, etc. He then custom grinds a cam specifically for your setup. Obviously the best option.

You can always go to other guys too if you don't want to go that route. My first cam I went to Vengeance and was more than satisfied with their help, knowledge and product. After speaking with Ron I decided to go with the VRX5 cam package and was very happy. Would still be running it now if my motor didn't crap out (NOT Vengeance related).

 

Texas Speed 228R @ 112 LSA.

 

Thanks for the input. I'll have to check them out

 

Mine has a TSP 228R 114LSA with a +2 grind in it. Combined with a set of PRC 5.3 heads shaved down to give it a compression bump. It sounds almost stock at idle, has no low speed surging, and put down 450 rwhp after tuning.

 

Nice. Simular to my 226/230 114+3. Pretty mellow idle, explosive midrange and top end.

Sneaky, they never know what hit them.

Ron

 

Especially since I am still running Z06 mufflers.

 

I just talked to Texas Speed and I have to say their knowledge on what would be good for my application was second to none. After talking to their tech Gary I decided to go with the 228R, thanks Nuke. I'll let you know what she pulls on the dyno..

 

I just did the 228R, ARH, LS6 intake, and RedTop injectors on my 2000 w/stock heads. Came in at 380 Hp at the wheels.

 

Ya I really like the sound of their lineup. I am restricted to the 224/228 version due to Cali emissions, but its still going to be a great cam! The 228r sounds ideal the more I research.

To answer your PM. The 228r is still going to have decent low end characteristics and really nice mid and top end power. So when you punch it, the car is going to be crazy. I never asked, but is the car an auto or stick? How you make the cam even better is with a stall converter in an auto. Here you will pass the cams weak point and be in the optimal powerband at all times! Kiss your gas mileage goodbye, but its going to be a fun time! I run a 3200 stall and the car is just waiting for that cam .
Furthermore, on my dyno sheets, the stock cam fell off at 5300 rpm. The 228r should allow the engine to go all the way into the 6000rpm range, or even close to 7000. Not sure on the specifics, but this is why you need good springs that can handle the cam. So in short, this cam is going to give you increase power pretty much across the board and add allot to the top end too.
So when you launch the car, if auto, use a high stall converter to be at optimal rpm, if manual, you find the sweet spot and go from there. Both ways will require nice sticky tires to make full use of the launch.
Assuming you drag the car some...

Thank god for high stall converters! The only way id consider a cam that sacrifices some on the low end is the fact that you can bypass it with the high stall converter. This makes a cam like the 228r a great decision. Very streetable and powerful. On a manual, you have the control of the car to make it perform well.

 

I refrain from posting Dyno results because it always seams to open up a can of worms. Anyway here's my printout on my 228R. As you can see there's a lot of HP gain above 5300 rpm. I think this cam is just great, I have no complaint of any kind with it's performance.

 

^^^Looks like the 228r makes power to about 6400rpm in your case. Thats a big jump over stock! Of course heads and other things will make the difference in exactly how much rpm can be achieved. But Im sure a 1000rpm increase is a safe bet to say will definitely be gained over stock. What kind of heads/ head work do you have? Freer flowing heads will allow the cam to keep climbing.

 

That looks pretty good. I like that 300+TQ@ 3,000. Dose anyone think it would benafit from going with 30+lb injectors, looks like it leaned out just after 3700rpm. btw nuke my vette is manual so diffidently will have to find the sweet spot

 

Oh for sure, your definitely going to have to upgrade injectors. Im at 90% with just intake bolt on's! Not even LT's. I ordered a set of 36lb injectors so that even after a heads and cam swap I have room for future growth. IE: nitrous or FI.

 

Okay... So with bigger injectors would I have to do a high flow fuel reg/pump, Or is the stock equipment good to handle say 36lb?

 

I went with a little more Torquer V2 on 112.

 

My tuner says the stock pump is good to 600 crank horse. It will handle 36lb injectors fine.

 

Hey Nuke...who is your tuner?

I dropped my car off with Charlie at RPM

After telling him what I wanted, i.e. the most low and midrange torque I can get and still have some decent top end while being able to pass the Cali sniff test,

he recommended that we go with a 223/227 with 610/614 lift and 114 lsa...can't remember the advance ground in but think it was something like a +1

I already have a big LG breather, LS6 intake, LT headers, high flow cats etc...and we are doing AFR 205 heads with a trunnion rocker upgrade and Patriot Extreme springs...he say it should end up around 450 RWHP with great drivability and great average power...will probably get the car back tomorrow....feel like a kid before Christmas lol

Am honored to have Charlie tune my car...has a great load bearing dyno and is one of the best speed density tuners alive for LS engines.

I'll let ya know where we end up and email ya a dyno sheet ;-)

 

Sounds like a great set up! But id expect around 420 with that cam. I hope you prove me wrong of course! Look forward to hearing the numbers!
We have a similar plan. My cali cam will be 224/228 .581/.588 on a 114lsa. Im hoping for 410-420 with it and a ported set of 243's or Trick flow 215's. I go to Excelsior Motorsports in Escondido. Kushan is the tuner. He does wonders with these cars.
