To Cam or not to cam

[StroktWJ]

Hi guys,
I'm new to this forum and see a wealth of knowledge, so I'm hoping I can help some people out along with further my project.

I have a 00WJ that I am building a 4.6L stroker for, I almost have the short block buttoned up but wonder about the valve train. I have 3 cam choices and was hoping for some opinions.

00 cam
188/192 @ 50
.408/.414

94 cam
197 @ 50
.424 lift

or ordered a Comp 68-232-4
206/212 @ .050
.460/.476

The vehicle will be my second vehicle so not driven daily, I have also heard of people using a Mopar Magnum valve springs or an LS beehive spring? What needs to be done to the head to use the LS spring as I know these are taller, or what would need to be done to run the Magnum spring? I have a set of LS beehives but I am yet to mach anything up yet. The WJ will also remain EFI.

The thing is what do you want to achieve with this engine- huge torque on low revs, high power, flat torque curve etc.

if you are ending up with a high static compression ratio, just find the cam that gets your dynamic compression ratio down to somewhere between 8.0 and 8.4-ish :1

This will let you run on pump gas. the shorter duration cams will support more low-end torque... but they also increase the dynamic compression. its a balancing act.

Im fairly positive youre stuck with the stock cam as the cam retention system was changed in 99. I think you can modify it somehow to fit older and aftermarket cams, so I would look into that.

you can use a cam for the earlier engines you just need the timing set, cam bolt, spring and pin to go with it. Thats what I am in the process of doing right now.

Yeah I thought you would need other stuff to make it work.

Yes that is correct I ended up using the 94 cam with earlier timing set, cam bolt & pin.
