I have a stock LQ4 with a stock 4l80e in my car now. I have stock LS3 heads and a patriot performance 225/229 580 590 cam that I was going to swap in the engine with a 6.2 truck intake. I have a truck intake now. Do you guys think I will gain much or is this too mismatched. I bought the cam cheap so thats what I have at the moment. I was just thinking I should just swap the cam and sell the heads but I cant decide. Help me decide.thanks

You will be fine with that cam. Clean up your exhaust ports real good and you will be fine with that split. If the truck intake is cheaper go with that. I just did a ls2 with those heads and 11 to 1 and a little 224/224 cam and it is about 450 hp. Make sure you get some good double valve springs and hardened pushrods...lots of power left on the table with guys skimping on the valve trains.
