Well i can help u out with pretty much everything u'll need to no for the sbf swap, Although mines not a 5.0 its a 5.8 351w, but pretty much the same concept. The stock mazda rear will take a pretty good beatin but spining 1 tire is not for me=) and it is geared way to low for a 3spd auto, so make sure u do a 5spd or a overdrive tranny if ur not gonna swap rears right now im in the middle of redoing my 4link,rear bag mounts and shocks to put a 98 ford mustang 8.8 LSD disc brake rear with 3.27's instead of the 3.90's in the stock mazda rear. Wiring on the sbf's is very simple as long as u use an electronic dizzy, and the ignition box, everything plugs in from there and u have power to the hole engine, dizzy, coil, alternator. Let me no if u have any other questions,
