Those are factory originals yes. They're not design 3's.

 

But these are the 4 hole design

 

Right, those are good, a different design, perhaps newer than D-3's

Design 3's are 4 hole, not sure of the spread, but they're tall skinny and loud, w/different hats. ,

Different connector pic, -



Design 3 pick,-





But yea, the injectors your looking at have the newer style pintle holes.

 

I think I'm going to go with them

 

So f150s have ev1 injectors right? Im in the market for some and need them for my 4v. Want to get some 24lb probably I think thats stock on navigators.

Save that link, they closed up shop but there's allot of useful stuff on that site.

 

EV1 & EV6 have the same connectors & are interchangeable. I had a set of 19lb ev1s and when I ordered a reman set off eBay they came in ev6. Look a little different, but will plug & play. 24lbers will drop right in for ya. When you get your tune they can adjust for that.

Nice link Jbrew. Next time instead of dropping $110+ for a new set, I'll try that.

 

A single blade TB for a charger is the way to go. A lot of people don't understand their is a huge difference between; sucking air vs pushing air.

I am using a ported lightning throttle body (dual) I got off dave for mine. Since my twins will be pushing the air, the throttle body has less restriction. Especially compared to a roots or screw type blower sucking air.

I have a set of the 19# someone can have. They needed to be freshened up and cleaned, but I have no use for them.

 

I pulled my engine and I still can't get the bay as clean as brew. Maybe I am just too lazy.

 

I had a buddy put on a single blade and he the difference was very noticeable. I ran a stock on mine but if I'd kept it, the TB would have been the next upgrade.
