N/a ls3 418 stroker cam kit help
I am not going to sit here and suggest any specific cam or even try and give you specs. I would contact the people that do this everyday. Nick at BTR, Martin Smallwood, Cam Motion has a few nice off the shelf grinds (As well as BTR, etc), Summit probably has a few grinds that would work well for your build... But don't under cam it. Need to take into account the engine size, compression ratio, etc. Both of these will eat up duration so putting for example a 23X/24X cam in the thing might be a bit small.

I would probably choose between these two:

What heads do you have and is this for a truck or car?

Without knowing the rear gear ratio, auto or manual trans, car weight, converter stall (if applicable), and intended usage of the car, giving cam recommendations would be as accurate as recommending the winning lotto numbers. A LOT more info on everything is needed before anyone, even the experts, can recommend anything....

it’ll be for a c6 corvette, auto trans, and it’ll be a street build!
It's going to need a 4000-4500 converter with the Hi Ram you want to run. The 238/256 113 cam I have will meet your goals with the rpm range and a 4000rpm converter. You would def want to run hollow stem int valves in the 823 heads, that would be cheap/easy power I wouldn't go nuts porting the heads, but doing some work to the exhaust and getting the bump out of the int port along with a good valve job will get the most out of them. If you want more, I would buy a completely different head.

Gotcha. Ill stick with the two cams i mentioned. The summit cam and btr cam. 230s duration will be solid on the street in a 418. 823 rectangle heads call for a good split between intake and exhaust so high 240s or above is good to allow the engine to breathe.
