one of the things the guy was bummed about though, seemed to be he felt the torque was soft in the lower rpm's. i think he was hoping to get to ~575hp and also pick up the torque curve a little too.
The low end TQ was pretty poor.
I don't think I can point the finger at the SV intake alone for that.
As I said, the bracket 416 I did a few years ago had that same intake on it with only a quicky port match....... And that motor was up 100ft/lbs at 4000rpm.
Peak TQ to peak TQ the motor I did was only up about 10, but the bottom of the curve was much better.
