I wanna do a cam in my ls6 v what's the best for a DD anyone running a vrx3 cam? Looking for most hp cam setup an other supporting mods

 

VRX3 is a great cam for a daily. Mine a little bigger and doesn't hit until a little later in the rpm's (2100-6800) but both the vrx3 and vrx5 would be perfect IMO. I love big cams but too big in this car is pointless unless u plan to run track only. Dyno queens are cool but u wanna make power where it's needed and not just peak power especially in a street car.

 

Its a little more expensive but the g5x3 makes awsome power and is very streetable in my op. I made 429/395 with the g5x3 ported stock mani, ported tb, full exhaust and a tune, through the stock airbox with a k&n filter.

 

How much power did the ported intake an tb give u? I prettty much have all the same stuff done besides the ported stuff an I only have 351rwhp

 

Before the cam and ported tb i dynoed like 377/374. I added the cam and the tb and put down the 429/395. So i couldnt tell you how much the tb gave me, and the first time i had the car tuned was after i put the full exhaust and ported mani on. I never did a baseline pull.

 

Who/how are these stock manifolds ported?

 

I had mine done through peak speed there a sponsor on here, and they smooth out the inside. On mine i had them do their " radical port job" which they take out the center posts on the manifold. I believe their website is peakspeedshop.com.

 

Its pointless on an LS6 intake manifold. The LS2s are more restrictive from the factory so they see good gains from it.

 

I'm going with the TSP Torquer V3. Should net me around 400whp with long tubes and exhaust.

 

im making 447 with a thunder racing 219/230 .605 .604 117 cam... ls2... drives like stock with a small lick, but can still do 1-4 skip shift with no bog

 

What ported/aftermarket heads and what size fast intake?

 

i have a set of ls3 ported heads, intake exhaust ports and combustion chambers as well... my v has a volant intake, i ported my stock tb, ported the ls3 intake, running pacesetter 1 3/4 headers, gm exhaust. with a the thunder racing cam (mine is made to be a true cam only with factory cats and factory exhaust. 219/230 .605 .604 117 which is close to an ls9 cam 215/230 .578 .578 121.5 i believe. im around a 10.3 10.4 static compression. i chose this cam as i will be running a tc78 under the hood, construction for that to begin in the late fall and or winter. the car was tuned with bad o2s and is getting a retune soon. will be posting the numbers up after a tune. a fast is a waste in my opinion unless youre running 7.0L plus

some say thats low, i dont think so for a ctsv as livernois has a ctsv 07 with the same heads, larger cam, and kooks 1 7/8s. my cam is all about low and midrange as peak in a heavy car is useless. car made 448 and 418 hoping to hit 460 425 with a retune... thinking about gutting the mufflers out as im running a gm performance cat back... i hear more intake and motor on the car than exhaust

60* and 42 percent humidity

 

Honestly your best bet is if your gonna pay $400 for an off the shelf cam just get a custom spec'd cam. The prices are about the same only like $20 difference but you get exactly what you want and need to make your goals. Best of all its made for your setup and is what will work best for you.

Dont get me wrong though off the shelf cams are pretty damn good and have made names for themselves, but im a bigger fan of cust. cams just because your able to get everything out of what your setup, and its tailored to your car.

I've had Pat.g Spec me out a few cams and all of them exceeded my expectaions and goals. To say the least I'm very happy with his work and will be continuing business with him!!!

I don't know what all goes into specing out a cam. I don't know if they pick a number that's optimal for an engine, for the car, or what not. I had a friend pick out a cam from a sound clip... When I considered my cam, I wanted low end torque as a v isn't the lightest car gm made. I wanted excellent street manners and sound close to stock. I chose a larger split as ls3 valves are much larger than catherdral head valves. Lower intake duration was needed and needed a longer exhaust duration to keep the velocity up. .600 lift area seems like the sweet spot in getting a suffient air into the motor and the lsa to spread my power from idle to redline. Specing a cam you take weight gearing drivablity sound where in the power band you want to make power power adders etc into consideration. To spec it to the motor you need to know cfm of the heads you are running and all the bolt ons as well. Its a give take thing. I sacrificed top end, that way when the V gets a turbo I am not dependant on boost to make the car move, but the turbo will make up the top end later

 

Looking forward to this project. Keep me posted.

 

^^^ who still has skip shift???

 

I was just wondering cause you failed to mention the heads and intake lol. it sounded like you made 447 cam only with that cam and i was like yea ok lol

 

you failed at typing failed... among other words lol. i personally think if its an ls6 with stock heads intake and exhaust, cam motion has a great 224 228 .600 .600 LSA 113. great drivability nice lobe to it and pulls hard. again my cam is going FI later down the road, and i dont care to spend the extra bread to make a few more horses later. looking back now, i could have went with a 224/236 .609 .607 117 and made a little more... in my experience, rectangle ports do not need the higher intake duration as the valves are 2.165 compared to a 2.00. not to mention the intake port is 265 if in not mistaken.

from what i have seen, you cant run as large of a cam with l92 heads, as the piston to valve clearences are closer, esp when milled... l92s do better with the larger bore ls3s (4.065). the valve shrouding sucks with a 4 inch bore, but trickflow and afrs make the best power as you can run larger camshafts, and keep the factory compression, have larger intake ports, better port velocity, and still have a larger 2.08 intake valve... they seem to be the only heads making 500rwhp with a 6L or less
