I have a 2000 camaro ss and am currently running stock heads, stock injectors, slightly ported throttle body, LS6 intake, long tube headers, a 228/232 duration 588/595 lift 112LSA cam and a full comp cams valve train. The combo runs decent but not really happy with it. Keith McCord from STL tuned it, the car did around 360hp without locking the stall converter (I was told you could add 20-30hp) so it should be around 390hp to the wheels. Im not that worried about the dyno numbers, every dyno is different and you can make them say whatever you want. My problem is I don’t think the car pulls like it should, it doesnt seem to pull much harder than some bolt-on cars. I am thinking about changing a few things this winter. Here is where I need your advice!! I am going to port my heads, so I can get a little more flow and hp. I am also thinking about raising the compression to around 11.1 and installing forged pistons and rods. I will also go to 36lbs injectors or something close to that. Do you all think I should go with a bigger cam? I am replacing the stock 6.089 inch rods with 6.125, how much or will that affect my compression?? Changing the rods will put me at 1.69 instead of 1.68 rod ratio so not much will change there. I am also thinking about installing 1.8 rocker arms or will I need to if I just go with a bigger cam??
I just want my car to pull harder in the mid and high end rpm range, I will change my converter if I need to it is a 3200 edge converter. I guess the main thing I want to know is, is upping the compression worth it and how much will I gain by doing so, is that the right rod choice, can I spray a 125 to 150 wet shot with 11.1 compression and should I change my cam??


Thank you very much for your advice it is greatly appreciated!!

 

I would stay away from the 1.8 rockers. If your forgeing the moter it will take a 150 shot all day long. I think the cam you have is good enough. I say port the heads, get the compression up a little and hit it with the go gas and you should be prety happy.

 

thanks

 

Get pistons with -2cc valve reliefs so you can mill to 59cc to bump compression.

 

thanks i forgot ask about the pistons.
