What carb and intake for 5.9 Magnum?

If you go to Comp cams website you can sign up for cam quest and see hp vs torque curves of different cams.

I took my 94 360 mag to the machine shop a couple of weeks ago.
Cylinder bores were excellent with lots of cross-hatch still showing.
The rod bearings were a different story the upper side of the bearings were starting to show brass. Ended up turning the crank .010".
I put standard kb 107's in mine to up the compression, and the pistons weight difference required balancing of the recopricating assy.

To run a 4-speed you will need a flywheel for magnum balance, they run a little over $300.00
