Re: 91 5.0 ho upgrades
You got some easy questions and you mostly got all the answers dude.
1.Explorer intake be cheap and great upgrade (same as cobra)
2.Heads....depends howmuch HP you looking for?
3.I like E303 cam, friend made 300 to the wheels with Ecam and AFR165 heads.
4.Mass Air , be better to swithch it over to a bigger unit(like 75mm) if you upgrade to bigger heads and Intake,throttlebody. Get a universal unit that ca be recalibrated for bigger injectors.
Give a little more detail about your project and you might get more answers.
