Anybody know if theres a supercharger for an 1984 3.8

 

I do not know.

I moved this here from the FIF section, but I'm not sure where else would help. The sixxer in the fox was rare.

 

You can do it, but there isn't a "kit" per say.

Switch it up to a blow thru style carb, use a carb bonnet and pick what blower you want to use. Then you'll have to run your own inlet piping to it.

Super Six did a carb/roots blower set up based on my old M112 boxed upper in their V6 '79 fox coupe. A bit dramatic and mostly just to say they could do it.
