Well 1st are ya gonna keep the EFI ( if you have emissions testing you might have to) 2nd how much $ can you spend becuse to improve the "speed density" EFI system you have now there is not too much you can due with it, you can convert to "MAF" mass air flow for around 600$ and due what ever you want , cam, heads, timing curve......i converted mine form EFI to a carb very simple and i did it all for around 900$ carb to pan . it will turn over 6,000 and as beat as it looks will smoke must newer V-8 trucks on the road

Not entirely true. There are many bolt-on aftermarket performance products that will work just fine with your speed density EFI. Cams and heads are a little tougher but as long as the cam lobe separation is kept within certain tolerances it can be done. Check with you performance parts distributor. Yes conversion to MAF (mass air Fuel injection) virtually eliminates these concerns but it doesn't mean you are stuck with whatever perfomance your stock speed density truck has. Cold air intakes, Edebrock's Performer series intakes for the EFI Ford 302 and 351 truck engines, BBK's larger bore throttle bodies, not to mention the ignition systems and exhaust and fuel injectors are just some of the options you have. High performance has more to do with getting air/fuel IN and OUT more efficiently than anything so anything that will improve these areas will help.
