opinions or best cam for ls2? I have a 05 ls2 out of a gto it has a edelbrock performer rpm intake a 2" carb spacer and a edelbrock 650 cfm off road carb truck runs and works good just want more power..
I think im going to do new ported heads and cam or at least cam and new springs, pushrods, rockers..
what is a good cam for a stock bottom end ls2 to get most power but keep reliability. I don't mind a lot of lift its a off road race truck so I want it to be knarly thanks for your help

The most popular cam for milder LS builds that I have seen tend to range from 220 degrees of duration @ .050" to 228 degrees of duration @ .050" of duration. Any of those cams will work wonders on your combo. If you can find a good deal on a "220 cam" or a "224 cam" snap it up. It can have a lobe separation angle from 110 to 114 with that Performer RPM intake and it will run great.
However, if you go to a Victor Jr intake manifold down the road for more upper RPM power, then the cam will have to be more tailored for your application.
In addition, I did some testing with spacers on the Performer RPM intake and found no gains with any spacer.
Lastly, get yourself a 750 CFM mechanical secondary Holley based carburetor, you will pick up some free horsepower there.

Hey, for folks that are not looking for max power, they have their place. Who else has a off shelf grind for 300$? Lol. For folks looking for max power, those cams are not a option!
It is as we have 2 groups of LS swappers:
1: want it to run good but not be competitive in the racing world.
2: want it to get every oz of power possible.
That's pretty much how I have summed it up. Maybe I need a cut from edelbrock a groups 1 and martins group 2. Lol

ok well I would like to get or squeeze every bit of horsepower out of it I can with only 2-3k but I want to try and keep it as reliable as possible.. should I do heads and cam? should I do do cam and carburetor? and I actually drive the truck mostly at higher rpms
I am screaming that engine for long periods of time. right now its got a lot of torque and power in first and second but doesn't pull very well in third so I think gearing and some more hp and she should be a rocket

You simply do not have enough converter for max power, and as at as reliable, a smaller cam fits that category. We need to know exactly where you stand. I would not think you want to rev to the moon in a setup like that. Mid and early power is what I think you need.

im still learning this whole ls engine deal and especially carbureted..so that's why im asking you guys.. what do you mean I don't have enouph converter? you saying I need a higher stall speed like 3500? and as far as rev I have taken it to 7k a few times going from first to second but for the most part 4800-6200 is about the rpm range im always trying to be in cause that's where I feel she screams

I'd say pull those 243 heads off and send them to advanced induction for the 226 cc program, get a custom cam from tick and if money allows a bit bigger stall and carb.
