408 Stroker

Why build a stroker? I owned a jeep for awhile and had a complete good know magnum to swap in. Realized i didnt want to upgrade the whole drivetrain. So i left it alone and got rid of the magnum.

The stock 5 speed will likely grenade, then the axles, driveshafts, the transfer case is probably a bit too weak also. Why don't you just build the 360 and use the new pistons you already have. Throw some magnum heads on it if you desire. Or find some X or J heads and have them cleaned up and put a mild cam in it. It'll be very cheap since you have most of it from the sounds of it. And if you truly need more power you can always build a 408 while you are driving the jeep around with a 360.
