Any reputable machine shop should be able to machine your pistons as well as balance the rotating assembly. Stock valves are inconel. Unless you are porting the heads and using bigger valves stock will be fine.

The stage 2 GH cam requires at min .050 valve relief on the exhaust valve at stock valve recession depending on how your head is set up will determine the relief needed. It is a good idea to do at min .050 across the board for reliefs. To take full advantage of the higher lift you are going to need extensive port work done.

Valve springs swamps stage 2s, irate high rev, comp beehives all will get the job done.

Are you trying to be competitive/ win or just have fun. Depending you will need more fuel and air for the class. Properly setup chassis will go a long way as well

 

[turner97]

YA I'm looking to win

Whst chassis mods have u done so far? Limited rear travel/solid rear? Traction bars, d shaft loops for safety. Move hitch point as far forward as u can.. whats ur gearing and tire size? Lockers or welded diffs?

 

[turner97]

Solid rear,traction bars,loops,and hitch is moved in to where the hook point is 6" inside my tailgate 4:10s with 285/75/16s running duals in rear Detroit locker in rear spool in front and front has one leaf spring so its its lower with the weight box

350/200s with a street cam, Gen 3, good port job and a good machine shop putting a true 5 angle valve job will get you there, a few guys are running Ferrera valves and Manley springs now matched together. Put a good balancer on it and a swamps IDM to keep it at High rpm will make a solid 750hp...

750 on fuel is stretching it with 350/200s with any turbo setup much less a s464...

 

[SDS97_7.3]

Yeah, I'm not seeing him getting anywhere close to 750 with that setup

I'm doing a 475 tapered down to a 2.5 this year

Wouldn't he get more benefit for a stage 2 cam?
