No you want a comp 239, retard 3 or 4 degrees! That way the power band shifts to the left..IE lower in the rpms, but you still get the duration and lift
Just gotta think it through lol..The comp 239 is a high rpm screamer, but it has been retarded enough to run in a stock 4.0 xj..so your stroker 4.7L will have no problem with it!
He's running it retared 3*, in a stoke 4.0. You will love this cam! When you retard it, it'll idle just fine, a little lope but no vaccum issues or anything like people "claim"..and again since your running a 4.7L..more cubes, it'll turn this cam without issues! Hes got a 97+ which are even more finicky..and he's idling at 800rpm without issue lol. Get the comp 239 and retard it a few degrees
And Pm me I've decided I'll be swapping in a om617 diesel..a Merc 3.0 5cyl
So I'm selling everything I had to build my 4.0 stroker. I'm on jeepstrokers.com as well, same user name! You can buy my whole LSx valve train, its ls1 stockes,retainers & locks and Z06 springs which can handle any aftermarket cam for the 4.0.
For install you'd need to open up valve seats to 2.00/1.55 and grind down the spring seats so you get a 1.75" install height..its as easy as that lol, these will add 2.8cc per combustion chamber because they are tuliped undersides, thus giving you more room CC, thus a slightly lower compression ratio, thus you can tighen your quench height up! Shoot me a pm, I've got alot of stuff that I'm gonna sell, 99% of its all brand new never even opened lol.
