Cam,pistons..

So I'm planning in the next week or so to pull my motor and put new lifters,billet cam,pushrods,valve springs. And coated/flycut pistons.

Now my question is piston fly cutting. With the stage 2 cam.
Some say its required and some don't.
Opinions and recommendations please!
Anyone running. Billet cam?

I did it on my 6.4 just for piece of mind. I say do it

I'm looking at doing the same thing, I would just go with the fly cut pistons to be safe.

What cam did you get?

stage 1 colt cam

I sell stage one regrind cams (webb06's) and stage 2 billets. A have seen valve marks with stock cams and do not recommend them without fly cutting. Stage two is a must if you want to run it.

Like Webb said peace of mind. If you break a u-joint and over rev your engine, do you want to be tearing it down because you didn't have adequate clearance built into you engine and floated a valve?

I can set you up with a good deal when your ready.

True. I'm getting them just wanted more opinions.
I'm wanting a fun (nothing crazy) reliable daily driver.

I know the Holder guys run the stage 1's. There are a few people running them here, haven't heard of anyone fly cutting for the stage 1's. Hard to plan around a theoretical mishap. If you were worried about the over-rev you could just do stiffer valve springs instead of fly cutting the pistons... JMO.

If you call and talk to Geoff at Colt Cams, he will explain if you need it or not. (He is the owner/cam grinder.)

I run his stage 2, which still does not require piston machining, as it is still using a stock cam...just reground.

If you were NOT replacing the springs, I would say get the pistons done.

But...I always like to error on the side of safe when it comes to metal to metal contact...so I have machined pistons.

One more thing...pending on whoever does the machining...they can remove whatever amount you want. (Elite does different depths of fly cutting for different cam profiles.)

We run the stage 1 all the time with stock pistons with no trouble. The stage 2 is a toss up. It's very close to the same grind not a lot different, cut pistons would give you that assurance but Geoff says they are not needed.

Who is doing the fly cut pistons for you Josh?

Ive been looking at either rcd or elite. I don't know yet..

Jared at RCD told me he highly recommends flycuts for any cam they sell.

I have stage one cam, without fly cut piston's and zero issues, they where made to use with stock cut piston's.

Anyone know where to obtain a cyl hone for the new pistons.

Bump

not to derail but has anyone noticed a difference with cams over stock?

Yeah, I'd like to hear from people with them.
Spoke with Morgan and he said the notice pretty big difference.

Anyone get a home for the new pistons?
