Jeep Strokers

Brand new member, long time reader, looking for any advice people can offer.

Amateur first time engine builder also. Sorry If I overload this with info , if theres anything I missed let me know.

Trying to build a 4.6L low C.R stroker, preferably running 87-90 oct. pump gas, mostly street and some 4 wheeling. Im having trouble selecting a cam shaft. Heres what I have for parts so far:

- 87-90 4.0 block .030 over, “skimmed” flat
- 7120 head, decked, 3 angle valve job, etc
- 99+ intake gasket matched + 62mm throttle body


Cleggs stage one 8.8 C.R stroker kit:
- Eagle Crankshaft 3.895” stroke.
- KB424C030 Hypereutectic -27.5cc* 
- “Remaned” factory 4.0 rods
- Hastings moly rings
- King rod bearings
- Clevite main bearings
I would like to stick with these components 

Heres where I have concerns:
- Comp Cams 68-232-4 Cam
(206 int./212 exh. dur. @ .050”, 0.460 int./0.476 exh. Lift) CWC casting
- Comp cams 822-12 Lifters
- Comp cams 3219 “Hi energy” timing set
Springs to go along with Cam choice:
- Mopar performance valve springs P5249464
- Mopar retainers P4452032
- Mopar keepers P4529218
Purchased these parts new off marketplace for cheep. 
Not sure if the cam and lifters are what I want to use anymore. 

Ive heard many horror stories about Comps quality and have had local machinists recommending to look elsewhere for cam and lifters. Im sure everyone’s aware of common issues with collapsed lifters, wiped lobes etc.
Also I’m not even sure if this cam is a good grind for what Im building TBH.

Should I look for a custom ground cam?, would a stock cam do ok? Is a mopar cam an option? Am I worrying too much? Probably…
If anyone could throw out ideal cam specs for this set up it would be hugely appreciated. 

Ive also seen Russ mention that the -27.5 dish on these KB’s is too much? Although I believe he was talking about a 4.0 not a 4.6 stroker.

I’ll find our comb. Cham. Vol. and deck clearance later for the stroker calc, as of now using default numbers I get 8.61
With .051” H.G (A bit low) or 8.81 with .041” H.G (better), not accounting for material taken off the head and block surfaces (shouldn't be much)

Like I say any insight is hugely appreciated.

Now Im stuck debating if I should even use the pistons that came in this Cleggs 8.8:1 kit.
Punching in the numbers I have .072” quench (no good)
I think I’ll contact Russ, I might just end up buying new pistons, cam, and lifters from him if he can provide.
I wouldn't mind a higher C.R running 89-91 oct. fuel.
Like I said mainly street use and some 4x4ing.
My #1 priority is reliability, thats why I'm thinking of ditching the comp cam and lifters.

I’m out of town this weekend at my ranch in Big Bear but you’re still welcome to shoot me a call or email and I could go over some of your options with you.

Thank you Russ.
I’m going to drop the crank and one of my assembled pistons in the block this weekend so I can measure deck clearance and calculate my deck height from that. I’ll measure out my combustion chamber vol. as well.
That way I will have all the info needed for selecting the correct pistons.
Looking forward to doing business with you.
Enjoy your weekend! Take care.
