Need help choosing a cam for my 408, it will be NA. I want the best match for my setup not overly big not too small, but something that matches.

Lme LQ9 408
Callies crank
Callies rods
Wiesco forged nitrous pistons
NPR stainless chrome rings

L92 ported and polished heads with ferra valves(most likely or ls3 intake valves and stock exhaust valves)
Prc .650 dual springs
Holley Hi-ram intake
And 1 7/8 headers

And cam, or valve recommendations would be appreciated, also would roller rockers be beneficial? I want something reliable that works well together.

 

What is this going into? SC/EC?

 

EC 2004 Silverado SS

 

What transmission? If auto, what stall speed and rear gear?

 

I would contact Pat G on LS1 Tech and get him to custom spec you a cam.

 

Get one spec'd best thing u could do

 

FLT 4l65 lvl 6
4.10 gears
And circle D 3000-3200 stall

Doesn't he charge to spec cams? How much?

 

Like 25 bucks its worth it and if u buy his spec'd cam the 25 comes off the cam price

 

Hmm, might have to do that. any thoughts on valves or the roller rockers?

 

For that setup, with that stall speed and your goals, I would recommend a our 231/236 Camshaft. The Cam itself runs $389.99, or we can custom spec one for the same price.
