I'm gonna jump in here 'cause I'm an old guy and this is my take on it, back in the old days is was a matter of parts availability and price, the sbc was cheap to build, small in size so the fit was easy, rear axles were another story, 10 bolts were weak and 12 bolt or 8 3/4 or danas were expensive, 9's were like trash cans, they were in nearly every driveway in town (this was in the 60's) and could be easily narrowed to fit with a vast selection of gears. Now it's the 8.8, you want a stout rear with inexpensive gear choices there it is, again one in every driveway. The sbc in a fox was popular because the fox is light and the camaro was not. I've heard the claims about the chevy engine being faster in a ford ( built ford tough with chevy stuff), now you have the LS engines, I have to say they are impressive for cheap horse power so they get stuffed in everything, cheap when you compare it to stuffing a coyote in a car? Hot rodders have always been a cheap bunch, if you can make it faster cheaper they will do it, I do object to transplanting chevy stuff in a ford but it's not my car so do what you want, it's all cool, it's all hot rod'n. The cost to stuff an LS engine in a vehicle vs a coyote (just to compare modern engines) is negligible. Now just imagine the fight that would ensue if you stuck that nissan V6 with a hair dryer in a fox! It's all hot rodding. Enjoy the ride.
