Has anyone ever used msd coil packs? Also what's the best performance mods for a 4.6 V8? I got a tuner and gotts mod so far

I had a 4.6 in my old Mustang, it had cold air intake, throttle body, underdrive pulleys, upper intake elbow, SCT tune, headers, X-pipe, cat-back and more

The headers and throttle body made the biggest difference, I plan on installing both on my 5.4

Never tried the MSD on these engines

I have a 97 Cobra and on the Mustang forums it is recommended to stick with the stock Ford coil packs. I ended up changing over to a COP setup and it looks a lot cleaner IMO.

What is a COP setup?

Do you know if the old 4.6 mustangs are the same as the 4.6 truck engines? I really wanna get a full exhaust and im looking into a new tuner

I have an 03 mustang gt with MSD, made a pretty big difference in HP and fuel mileage.

COP = coil on plug. MSD has a bad reputation on SVT Performance in the 94-98 Cobra forum. Guys have had a lot of issues with MSD coil packs. I was putting 452 rear wheel hp down with mine on the stock coils and there was no sign of them loosing steam. Just my 2 cents. I believe that the car and truck blocks were cast at different plants at one time so you would have to check a little deeper into what is different between the two.

Any one have any info on the new 4.6's really think a intake/heads swap would give a nice litle boost to our trucks.

Did you do the coil packs or wires and distribute?

NO there are several versions of the 4.6, you should be able to find header and the rest of the exhaust for your year truck. stainless works may have something, but I'm not sure., I know they have full exhaust for the 5.4 and '04-'08 4.6's

Distributors were gone with the old pushrod engines, up to '98 I think they used coilpacks on the 4.6, but after that it was an individual coil for each cylinder.
