Need help plz -- 87-95 cam in 04 block

Post by alex420119 »

Hi,
I have a "base" stroker in my '04 wj. It's everything stock except 4wt crank and 258 rods. I've ended with 8.1 DCR which is little high for sea level and hot weather so I use 93 with a little to no ping. Now I have severe misfire/tap noise on one cylinder that I'm sure is dead cam/lifter (checked everything - plugs, coil, inj, wiring, compression ok).
I have a new mopar '92 cam that I'm willing to put in my stroker to bring DCR to 7.24. Is it a good idea? With almost stock DCR I will be able to use 87 gas without ping.? Quench is stock .072.
So I need your opinion or experience on:
1. Will it work with newer 99+ PCM?
2. Will it fit in '04 block ok?
3. Will I be happy with 7.24 DCR or will I lose all the hp/tq?

I've searched but it seems that nobody had done it before.
Thanks to all for all the info on this Forum! :cheers:
Alex.

3. Will I be happy with 7.24 DCR or will I lose all the hp/tq? You'll lose some but the ability to run the engine on 87 octane will make up for it.

Thanks alot!
I think it would be smart to use .044 gasket in this situation to gain some quench and 0.1 DCR.
