    He means there's alot of stuff that should have been done previously before the S/C. Intake, throttle body, injectors, gears.

    what he means is your setup is totally mismatched. Are you sure it is a 331? The heads, intake, TB, injectors are all wrong. You basically have a keg of beer and are trying to drink it with a straw. I would at least have 30lb injectors, a matching Pro M MAF, 70MM TB, and either a 96 or older Explorer, or Cobra, or TFS intake. How much boost are you seeing?

    If stock, you either have 2.73 or 3.08 gears. Check either the tag on the rear or your VIN.

    For the explorer, you can grab the 65MM TB. That's about it unless you deleted your EGR, as the 97 and newer are have no provisions for the external EGR.

    Hard to believe someone built a 331 and put the crap stock top end back on it. Do you have a build sheet or know who built that motor?

    Go look at what color your injectors are, that will help. You gotta chip tune or other fuel management system?

    I don't know who built it was just going by what the guy was telling me I know never believe people but sounds good and runs its balls off. just seeing what I could use or any add ons for some extra boost, it is seeing like 5psi when I put it to the ground

    Not to rain on your parade, but no one builds a stroker 331 and puts the stock top end back on. 5psi is a base level kit- I assume a 6 rib belt. Your stock injectors max out at 300 flyweel hp. The stock intake, TB, MAF , fuel pump, are all not sufficient or choke points. I'd have a talk with the guy you bought it from and get some specifics.

    Belive the black ones are 24lb's and they use a connector, i think if memory serves me right. I'm on my phone but you can google the color chart. And you need to go through and document what your parts are so you can truly find out what you have.

    I'm thinking you may be mistaken about your setup.
