I was looking on Jegs.com for performance parts and came across the Ford Racing MAF Conversion Kit. Well, they say it's necessary to have it before doing any performance modifications. Is this true? Also, what kind of benefits are there for MAF over the stock speed density system?

 

what rig/year and your goals. speed density can handle most things except for wild cams. so with some more info we can get a better answer to ya . also go here

It's a 1990 F150 5.0 EFI. I'm not looking for a ton of power, I just want to do some small things to my truck. Intake manifold, headers, dual exhaust, and maybe a cam and some valvetrain work. That's about it. I may want to go a bit more extreme in the future with like a supercharger or something.

What transmission do you have?

 

Its real hard to switch to MAF if you have the E4OD (OD button on the dash) because the computer controls the transmission and there isn't a MAF system that does this without alot of mods. You can have a custom chip burned for your SD system. Superchargers on SD are doable.
Your best bet it to call and talk with a chip burning company and see what they say about your goals. Maybe someone else will pipe up about a good company because I've not had any experience with em.

 

you can install heads,complete exhaust and a cam and intake setup. the speed density will work. your cam choice must have a lobe seperation no less then 114* though. some have gotten away with less but i wouldnt advise it.

 

What heads should I go with? What about rocker arms, push rods, and lifters? What cam should I go with? I have no experience with matching these kinds of parts together so they'll all work right. If you guys can give me some guidance, I'd be much appreciated! Thanks!

Well, you did mention that you may boost it down the road, so you don't want to do anything to will raise the compression ratio dramtically. AFR and Trick Flow have about the best head, out of the box, for a small block Ford. If you plan on staying with SD, then I would suggest getting a custom grind cam; Comp, Cam Motion, and several other cam manufacturers can do this.

Allow me make a few other suggestions that will help save you a few costly repairs down the road. The increased HP and TQ your motor makes is felt throughout the entire driveline (especially with a power adder).

If you have an auto tranny, I would suggest some type of shift kit or valve body. It will firm up the shifts and decrease the amount of heat generated from shift transitions. Traction bars keep wheel hop to a minimum and that will save your rear end and axles, and they work great if you have a set of sticky tires. Also, a driveshaft loop will contian your drive shaft if a u-joint or yoke snaps in two.
The few that I have mentioned will help your rig perform better with the added power, and allow you to enjoy if for many miles. Also, don't forget about aftermarket tuning once you have all of your parts installed. If you're going to spend the time and money to install good parts, then a chip will allow them to perform much better and safer.
