I have an 85' Bronco II with a 2.8L V-6. The engine is rebuilt with headers and a 2 1/2 " exhaust. I want to put a offenhauser intake on it with a holley 390 four barrel. Found an offenhauser intake for the late '70 2.8L v-6 and want to know if this will fit my '85 2.8L. What mods may or will I have to do to get it to fit and work?

It should work. the offy intake should have no ports for the EGR, but if you are using the 390cfm holley you will have to dura spark the ignition and by pass all emissions stuff anyway. You will have to fab up a throttle bracket, but the upgrade is easy and worth it.

What year and model did you find that intake? Is it a stock part?

I don't think the offey v4 came on anything stock except maybe a mustang II but I dought it. I have only seen it as an aftermarket performance part since it uses a 4 barrel carb on a 2.8l(alot of carb for a small engine).
