Best Intake Manifold
What is a good intake manifold you can buy for an 1987 F-150 with a 5.0L EFI? But keep in mind I don't want to bust the bank on it, I have to buy other parts because I'm rebuilding the motor.

Unless you're going to convert the EFI system to "mass air", or reprogram the SD computer, you're pretty much stuck with the truck upper and lower.( ditto for other performance upgrades as well) Otherwise, Edelbrock makes uppers and larger throttle body's to upgrade the truck setup. Some of the one's built for cars, use the truck lower also.

Just swapping intakes also isn't going to do squat either. To take advantage of it he'll need to upgrade heads, cam, headers.etc. Which you obviously have done also. And the aftermarket intakes are designed to change the airflow characteristics, moving power band to the upper rpms, so in effect they DO affect the SD system. You likely have gone to larger injectors with that setup too, but I guess you left that part of the equation out ?

Thanks Guys, that alot of info. I do plan to change headers and heads. I already have a set of hooker long tube headers, and I'm trying to find some gt-40s. Aluminum would be nice but to expensive, so i guess ill settle for the iron heads. So what do yall think of my horespower numbers will be with these mods:
1. New Upper and Lower Intake (dont know what kind yet)
2. Gt-40 heads
3. Hooker Headers
4. New Cam (slightly dif. still scoping them out but nit to drastic)
5. Mac Intake
6. Bassani Y-Pipe
7. Borla Cat Back
8. Larger Injectors (or do i need to leave them alone?)

I'm running the Edelbrock truck 5.0 EFI intake and can tell you it made a huge difference in the way my truck runs but I'm running a full exhaust system with shorty headers so I'm sure that helped enhance the performance of the intake.
