2.8 turbo carburated!?

So this should be a fun one for you guys to try and figure out for me lol. I wana stick with the carburated motor building it up a little bit mainly head bolts and gaskets. Not trying to make a record breaker out of it but more of a novelty kinda thing. So I know I am going to have to go with aftermarket intake manifold setup obviously. But the main question is what free flowing carb would do best for the 2.8 with boost. I have looked at a few but this is guna be a first time boostin a carbed motor. Any input or advice would be great thanks guys!

Re: 2.8 turbo carburated!?

u will need the edelbrock intake with the holley top plate, u will also need the 390 cfm holley carb that u will have to modify for blow threw carb use.

the mods to the carb are pretty simple if u have knowledge of carbs
