Topic: witch cam to choose from

[sharpxmen]

so i presume it is a good cam the mopar one at 50 $
and  beside valve spring are they other mecanical mod needed to keep up whit this one
because i will place and order too if its good

it is more aggressive than the Hesco cam, I think (but not sure) Bounty Hunter and JFRabat are using the same cam but they can confirm

Duration: 268-268 @52 Degree
Lift: 480"
Centerline: 108

i read somewhere that some of the 4.0L jeeps had the cam retarded from factory to help with emissions, not sure if it's true or not but i also wonder if that is the case with the 2.5L and if it is would this cam be rather 0deg or not (i guess you would need to dial it to know for sure but again since they already installed it maybe they can provide some further information on this).

If I was going to put this Mopar Performance Cam in my 95 YJ, I understand I would need new springs. If I did nothing else to the engine, would sharpxmen's adjustable FPR with 19lb injectors work? I do have a AFR gauge to dial it in. What other hardware is required?  I'm not planning to shave the deck, I don't want to raise compression unless it is necessary. I am new to working inside the motor so any answers that can be dummied down would be appreciated.

Thanks
Bill

yes, on the YJ the adjustable FPR would work just fine for fuel adjustment - you will need to look for a better than stock air filter however.

Mine is a .450 lift 256 duration Mopar High Performance camshaft, but if I had to do it all over again, I would probably go with the 248 duration one, as I have read it has more low end toruqe.  Still, I am happy with mine...

[penske2704]

so i now understant that this cam is big and agresif i hope it will gave me torque at the right place and not 3500 4500 rpm i iam now in serch of stiffer springs if somebody is running alredy this cam it will be nice to ave a litle review
if posible  i think that whit ta kind of cam my jeep gona gona have choppy idle

Lobe centers: 110 degrees
Lift: 470

JF's
Duration 256
lift 450

the Mopar in question (i'm guessing this one needs a higher idle)
Duration: 268-268 @52 Degree
Lift: 480"
Centerline: 108

[penske2704]

maybe it is gona be to much of a cam ... doo you think 

[penske2704]

on this site the cam jf got the basic rpm is 1300-5600 but i wonder if this is the plage the cam is working on or the minimum rpm to be ..
if its to big i will make it regrind to lower specs but for 50 $ it is wort trying it

Mine is a .450 lift 256 duration Mopar High Performance camshaft.

Mine is the same, picked it up for a song years ago when a Chrysler dealership was clearing them out on Ebay.

that's too much $$$

[dwtaylorpdx]

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...
