Which motor would be a better choice if i was shooting for 300 whp and just as much torque ? I want to keep it N/A , Im open to head swaps , cams and bolt-ons . At the moment im leaning more towards the 5.0 for its larger displacement and ohv design . Would a new cam , longtubes , ORY , and cat-back get me to my goals with a 5.0 ? What would i have to do to a 4.6 to get those kinds of numbers ?

It's personal prefercence. Both can get 300 rwhp. 5.0 is cheaper so if youre on a tight budget then 5.0. Low end launch torq and room to make it a 347 go to the OHV, but the 4.6 can be punched to a 320+ something 324 I think. The 4.6 has better breathing in upper RPMs too. 5.0 Has a more muscle car sounding exhaust while the Mustang is loud raspy at times and almost exotic car sounding.

Not without a good set of aluminum heads like Edelbrock, Trick Flow or AFR's.

You will also need to change the upper/lower intake to reach 300rwhp.

If you are really going to do this post up some pics of your progress.

I know I would like to see it.

they both need the same things, heads, cam , intake ,and the supporting bolt ons to get to 300rwhp. difference is money, 4.6 are more expensive and harder to install.

Yep, both can get it, the pushrod would cost less!

If you wanna stay N/A. Go with a pushrod. Simple Trickflow or Holley package will get you damn near 300rwhp. Or you could piece it together like AFRs, good cam, and Edelbrock intakes. If you didn't mind staying N/A I would say do a 4.6. A bonestock 2v with a P1SC at 10lbs will get you around 380rwhp with good drivebility.
