I about have my mind made up to do it. I am running 4.10's and it would be nice to get a little more mph out of each gear being able to rev a little higher.
This may hurt my future plans for nitrous though. Dont know if the motor could hold together over 6500rpm's with boost and nitrous.
I think the truck before was capable of low 12's...ran the 12.6 with no weight reduction and also before it was tuned. Really hoping It may be capable of some high 11's or a 12 flat when it's all done.

 

Hmmm, what happens if I have a problem there?? I already have the pistons and rods at the machine shop being pressed on. Would I need different pistons?? Or what??
Can you tell I know jack about this internal stuff?? LOL

 

Bad things would happen then .. How to fix it ... you would need to fly cut your pistons. I'm not sure what that is exactly, but ... it sounds good.

 

The lift has less to do with valve clearance than the duration I doubt you'll even be close to having valve interfearance problems.Go with a set of 918 Comp valvesprings and pop for the titanium retainers the reduced valvetrain weight should prevent valve float and probably add a few more horsepower to boot.Be sure you get an adjustable timig gear and chain.

 

Well, that's it then. Unless someone chimes in and tells me somthing negative about going with this cam I will most likely be ordering it tommorow...cam,springs,adjustable timing set.....still thinking about the titanium retainers.Gotta find some more money..lol
You think this may help me hit my goal of 500rwhp or more??

 

PtV = destruction of the top end. Valves will collide with the pistons and screwup your work and such. Not good. I'd assume you'll be using dished pistons with the boost so you'd probably be okay. If you're using flattop or domed pistons (dunno why you'd go domed on FI but eh) they've gotta be flycut to clear the valves.

You're running a lot of lift and it'd be silly not to check it, it's your motor and do what you wish but you'll kick yourself in the *** if you jack something up at this point.

 

Check over in the internal engine forum a lot of those guys are running a lot bigger cams than what you are talking about with flat top stock pistons with no problems.Unless you've milled a considerable amount off the heads I don't think you'll have a problem,I'd post overthere to see if anyone is running that cam I would think that several are.If you needed to flycut the pistons it would probably run about $50 to $60 for the set on your dished pistons they would only be notched in two small places.

 

Are you actually running dished pistons?

He said the heads were stock, so I would think that would count milling them out. Besides ... it would be silly to do in a boosted pplication.

 

I will definatley check the P to V clearance on it. This motor has to last.
The pistons are dished..but not the entire surface..the area under the valves is flat with valve reliefs cut out then the rest of the piston top is dished.

 

Are you sure you don't have them in upside down then?
