thats crazy ive never seen someone do alot of performance mods to a 2.8 i bet it will scream for such a small motor. garuntee it will outrun most of us with our 5.0 TBIs even without the juice. i hope the bottom end is built to the gills cause thats two major power adders. should be insane

I should mention I am going to probably go to 670 cfm and also add a haltech 3rd injector unit.

As a side note , I have my current holley tbi set to 14psi , had 14 psi I should say. I used to have a gutted thermac air box/K&N with the factory cool air tube and I had cut the core support to allow cool air to enter. After I installed the fullsize 305/350 airaid style assembly my Air fuel ratio gage wouldnt even read rich at full throttle. Needless to say this new air cleaner assembly flows like a mother. Just look at it. It has a ton of volume after filtration. I bumped it to 15 psi a few days ago and its still not quite as "fat" as I can go. Would be a good Idea for you guys. Plus they are on ebay right now for 89 bucks. But they might not fit under a f-body hood.
