Good hp, but the torque sure suffered.

it was re-cammed with a smaller cam tonight. It'll get a dyno tune again shortly.

New cam is 224/230 .581 .592 -110

I know it's a 5.3 and your not going to get staggering Tq#'s
I think a 6.0 running 394hp to the ground is going to have closer to 400 for Tq. and these big boats need all the Tq they can get!
