    Head/cams/intake swap vs Supercharger

    Did a search on this, but didn't seem to come up with much. Has anyone done only some old school work to their motors like ported heads, different cams and maybe a ported or other type of intake vs supercharger?

    I'm going to go on a limb and figure that there is not alot of this going on because of the huge amount of torque required to move one of these cars so the SC is a better choice. But still, just wondering...

    Census here is to go with the supercharger like an Eaton swap. Will cost less than beefing up the motor.

    I myself am building a bored 5.1 forged motor and staying NA instead of going with an SC only because my motor has close to 200k miles on it. No point of doing an SC when something break and then be SOL.

    What kind of heads/cam/intake are you going to use?

    Blower will yield more HP per dollar for sure. Mod motor work isn't cheap.

    +1

    Eaton swap will cost you roughly $4,000 - $4,500, will yield 420 - 430 rwhp.

    A built N/A mod motor (cammed big block stoker) might net you 400 HP on the high end, but it'll cost you $10k plus to get there.

    That sounds like a sweet combo!

    I don't hear about too many people porting the intake. I know on my 5.0 Foxbody, porting that lower intake made a HUGE difference.

    There is some power to gain from the intake being ported but it's more or less a mod to make other mods benefit more. Such as the intake spacer, it doesn't do much on a stock motor but if you add an intake, larger TB (which I going with a bbk twin 62mm unit) and headers it makes the mod a lot more effective and efficient.

    I ran ported heads, 98 Cobra cams and both a NAZ PSRI and my own ported long runner. Go sc, you'll end up there anyway if you're even asking...

    I would stay away from the BBK throttle bodys, Injected Engineering has a ton of them off of customers cars that leaked thru the butterfly shaft and caused all kinds of idle problems on the dyno!

    I would go Accufab, or Draggon

    Accufab FTW! Pricey but worth it. Got one on our 03' Cobra.

    The Ford DOHC motor from this era can breathe pretty OK from the factory, at least enough so that porting bits won't get you stupendous goals due to the cam simply not being hot enough. I believe that if you can spec it right, a cam swap would be a huge benefit, but when you are talking about four camshafts and all that supporting valvetrain, that's a lot of money.

    Also, to really make this car scoot, you're going to want to increase your torque across the board, but particularly in the lower RPM range, and without adding cubes, that's gonna be a lot harder to do with internal engine mods than if you just toss a roots blower on it. The 4.6 is just too darn tiny to make a car this big really move, in any of the N/A configurations it was built.

    Maybe the single blades, not the twin bores. I've had a twin 65mm BBK (Thank you Glassman!) for the entire time I've had my car. Not a prob throughout any of my upgrades.
