I am having my 2006 F-150 5.4 3v Built ,Copra Crank, Manley H beams and pistons and all the other good machining fun stuff done to the heads and block. but i am at a bottle neck I have not been able to find a suitable upgrade on the intake manifold side, does anybody now if theirs an adapter plate from a Mustang 4.6 3v to F-150 5.4 3v or anything I might be able to do any suggestions appreciated. . the dream is to get a blower one day so i don't want to brake the bank.

 

I guess the question is, with the work you are doing, is the stock intake even restrictive? It's not a particular pain point at stock power levels with a bit of headroom above. Exhaust is usually bigger area for gains, as well as headwork. I'd just save the money you were going to spend on an intake that won't net you much (if any) power gains and put it towards the 'charger.

 

I've gone +1 on all the valves and decked the block used the BBK 80mm TB it's going to be a few years befor a blower happens so esthetically the 88mm Ford racing looks better

 

I would like to know what kind of HP this is going to yield above the 300 factory. If you dont want to disclose a ballpark figure would be nice to hear.

 

just put a supercharger on it
