I have an 88 f150 4x4 w/ bone stock, low mileage 302, built aod, and a 4 inch lift with 33s. (Still speed density) I'm planning to swap some afr heads and a cam in before too long, and I was also wondering about superchargers. Since kenne belle, vortech, etc no longer make blowers for this era f150, would I be able to use one intended for a mustang with minimal modification? I've never been under the hood of a mustang, so I'm wondering, other than the lower intake, would anything else need to be changed? The 6 psi kenne belle kit designed for the speed density cars is the one I'm most interested in really.
I should also add that this truck is not a daily driver, and I'm going to stay with speed density as far as it will take me. My goal for this truck is to make it pretty quick on the street, and perform well offroad. I know that with my planned mods and my driving style, this stock bottom end 302 may not be long for this world. I'll just run her till she goes.
Any input is welcome, thank you.

 

You should be able to make it work, the biggest hurdle will be plumbing the single supercharger output to the twin truck throttlebodies... you will need a Y pipe of some type. The stock cam in that motor is pathetic but you can't use anything too radical, a stock 5.0HO cam with 1.7 rockers would be a good choice and would get you into a roller valve train as well which will free up some more power. A good friend of mine had a supercharged 5.0 Stang and it worked really well, the blower really woke up what was otherwise a stock motor with only 5-6psi boost.

That truck could really use some gears too.. 4.10-4.56.

 

Okay sounds good, I can fabricate a y pipe or anything else as long as I know the supercharger will physically bolt on and everything. As far as the cam goes, I was going to use a flat tappet from lunati, but now a roller conversion and the comp 35-349-8 is looking good to me, though that HO cam would be cheaper I imagine.
I have 3.55 gears and a high stall converter, but I do plan on installing 4.10s after these mods in an attempt to regain some low end torque.

 

The plumbing and bracketry are going to be your biggest obstacle. I lean toward the Vortech over the KB though. It will produce lower discharge temps and support more power for future upgrades. The HO cam seems to perform well, in a truck, when it's installed with a 2 degree advance. This moves the power down lower in the RPM range which helps to get these rigs moving out of the hole.
With ANY power adder, you should have a wideband to monitor A/F ratios so you can keep an eye on how the motor is being fueled and prevent burning a valve and/or piston. Most speed density kits come with an fuel management unit (fmu) and timing retard. You will want the FMU to be in the rich side and the timing retards to pull max timing in the initially.

 

You need the full roller cam assembly which includes the cam, lifters, spider, dogbones, and pushrods.. all of which can be salvaged from a junkyard motor or sometimes picked up on the used classifieds so yeah it should be significantly cheaper, you could easily spend $500-600 on new cam and lifters alone.
