Topic: witch cam to choose from

[penske2704]

going back to that cam question

this is be the biggest cam available so i wonder what king of problem i am gona go accross installing that 
and wat is going to be required to run this cam

[sharpxmen]

125 per piston, about the same as a good piston for a dirt bike...

On the other hand there are some really pretty good ones Like I used for about 250 for 4... Hyperutechtics...

Dave

looked to me that the price was per piston not the set of 4

EDIT: looked again and it is for the set, i hope they're forged for that price though
they have Keith Black forged pistons and are a tad cheaper for a set of 6 which would make the set of 4 about $400 but they don't have one :(

found some more info on the Mopar cams

P4529658

P4529659
Factory Engineered Hydraulic Cam and Tappet Package for Mild Competition Application 260-260-44* Duration, .460" Valve Lift, 108* Centerline

P4529660
Factory Engineered Hydraulic Cam and Tappet Package for Mild Competition Application 268-268-52* Duration, .480* Valve Lift, 108* Centerline


seems that all the Mopar cams were 108 centerline, so JF and Bounty's should be the same and it's a stage II. the 260 and 268 is stage III and seen it referred as xtreme comp somewhere, so i would think that there's no way you'd pass emissions with it but i'll give it a shot, if not i'll have to replace the cam every 2 years

Stage I Engine Package A

* Set timing for Maximum HP
* HP Hydraulic Cam 240" or 248" P4529656-657
* Valve Seal Package P4529661
* Valve Spring - Conical P4529217
* Conical Retainer- P4529217
* Low Restriction Enhaust
* Estimated 10 to 20 hp gain over stock

2.5L Jeep Inline 4 Engine

Stage II Engine Package B

Same as Engine Package A except for the following items:

* HP Hydraulic Cam 256" or 260" P4529658-659
* Centerline Cam with Bushing Kit P3690936
* Backcut Valves P4529212-213
* Richen Carb
* Engine oil Cooler P45292690
* Headers
* Estimate 20 to 30 hp gain over Stage I

2.5L Jeep Inline 4 Engine

Stage III Engine Package C

Same as Engine Package A and B except for the following items:

* Increase C.R.
* HP Hydraulic Cam 268" P4529660
* Ported Head P4529644
* Intake Manifold Attaching Package P4529679
* Good Gas
* HD Rod Bolt and Nut Package P4529817
* Estimated 20 to 30 hp gain over Stage II


so if you do all that could potentially be at about 180HP on a 4 banger  (cost prohibitive but according to this is possible)

I have also seen that is possible to increase the Intake size from 1.9'' to 2'' and have the intake/exhaust ported and polished

larger t/b and CAI is a given

his is a different cam; he has 268 duration and .480 lift and I have 256 duration  and .450 lift, so his cam seems to be even more aggressive than mine, and mine was suppossed to be most aggressive street version (read: emmission passing version) of the Mopar Performance Cams...  At least that is what they guy I bought it from said (but it seems right).

[penske2704]

there is no emision test here in canada so no problem for that
i just wonder de drivability of this cam 
and like i said if it is too mutch i iam gona find a other one and  put this one 4 sale

yep, it's a stage III cam, i ordered one too

well, here in Canada there's air-care (BC) - i doubt it will pass with that cam but at least i only have to do it every 2 years so if it fails i'll have to throw the stock one in

for $50 i can play with it, i don't mind, it's really something that you will not find in the future since they're all discontinued

[penske2704]

 

this cam is gona meet whit a 0.060 bore block and a rebuit head whit a pace setter headers and a 4.0 tb i thik its a good setup ... will see

[dwtaylorpdx]

The factory valve guides are too tall to handle the talles cams, so its
in cards to have the head done when you do the cam so the head can
be machined for the better springs... and to avoid the valves bottoming out...

My Head had to be relieved and the guides shortened by .090 as I recall....

I was looking at the Mancini Racing page that came up from the original link. I can't find the cam there. Am I at the wrong site or just blind. Any help would be appreciated.

Thanks
