Looking at your dyno chart, I am puzzled at the rather steep drop in torque starting around 5300 rpm. I would have expected a more gradual drop off in the beginning. So I am not enough of an expert here. I would advise a good valve train for any engine. Good roller rockers and new valve springs for sure. I suspect your cam would make more torque to a high rpm with better springs, therefore after stroking the engine I think it will peak above 5700 rpm. I cannot be sure though. Let's see what some others think.

Again I would recommend contacting BLYKINS. I think he could set you up with a better cam than you have and a better cam than comp will recommend. I believe he uses Comp and specs the lobes himself. He most likely can purchase your parts and ship them to you for about the same money. He builds a lot of engines and does it for a living.

thanks for the reply

the heads were ported by Ford Performance Solutions in Kali. Troy also ground the cam based on the head flow post porting. He installed the springs and my mechanic in the NL double checked the springs to make sure they were correct. I will contact Herr Lykins for his suggestion on what cam to grind.

at the end of the day, the fact that I am making 355 hp at the rear wheels behind a C6 tranny means I am making some pretty good power at the crank for a 351W.

All things being equal, should I expect to see a power bump by upping the CIs on this engine, keeping the cam, heads, and intake the same? I saw an episode of engine masters where they put the same heads, intake, and cam from a 350 on a stroker and it only gained 10 hp. Was that anamoly?
