Why did ford go with the 4.6 over the 5.0 in the mustang?

I was just curious

The modular 4.6 vs the pushrod 5.0 makes smoother power and is more efficient.It offers a over head cam design too. They probably lost a lot of money too since aftermarket parts for the 86-95 model were too over abundant which would cost Ford millions of dollars in lost revenue because we could buy better, power producing parts from suppliers other than Ford. You can buy a aftermarket part for every inch of a 86-95 Mustang. The parts list is huge for the foxbody Mustang.Although Ford does sell their own performance parts, I don't think their sales of these parts would even be 20% of the market. I believe the 87-93 Mustang GT and LX 5.0 liter Foxbody is the nicest looking design of all Mustangs since the 60, s.Everybody has their own opinion though.Ford made millions in the first few years after a new design comes out because they've got all the info at their fingertips needed for designing power producing parts. When Mustang performance part designers get a new model in their hands, its over

Mainly the 302 was going to have trouble meeting new emissions regulations for passenger cars (not light trucks though, the 302/351W stuck around for a few more years in Ford's truck/SUV lineup). The 4.6L could meet emissions regs, stock for stock it was on par with 302, and it was somewhat more fuel efficient as well. So the 4.6L was used as the V8 option for the Mustang. The 96-98 SOHCs were definitely not a match for the GM F-Bodies of the day, but with the P.I. Heads and intake manifold that came out in 1999, things got better. The 4 valve DOHC 4.6's. Matched up decently with the GM LT/LS1's as well, as did the 3 valve 4.6L's with VCT. The 4.6L is a good engine, it has good combination of power, fuel economy, and reliability (if you can overlook the spark plug issues).
