Mid 80s 318 four barrrel intake

Greetings,
I need a mid 80s 318 four barrel intake to match a 1985 Q-jet that is going on a 1987 318 Dodge truck.The truck runs very poorly and it appears to be the two barrel Holley.
If you do not have the cast iron stock intake, anyone have a good Holley 2 barrel from this era, for cheap?
Thank you all,
Tom
