Yes I'm talkin about an EFI 300, BUT I dont want one to fit in the box, I'd like to replace the UGLY box and make it look better and run better. I also wondered if I could change the throttle body from a V8 truck to the 6? They look the same, I'm not sure if it would bolt up or not? Has anyone done this?

If you are talking about a complete cold air intake from K&N, I do believe that they make one, its about 200 bucks or so. Go here Performance Parts Online for Cars and Trucks - Performance Center, I think thats the website I saw them on. As far as the throttle body, the one from the 302 will be your best bet as far as fitting will be a little larger, but i don't think it will make much of a difference.

Well, an interesting note.
SS in a past post, mentioned he removed the air tubes completely from the throttle body, dynoed it, then compared that against a run with the tubes in tact. Made no difference.
There are universal K&N or other brand airfilters, and there is universal aluminum tubes, would imagine you could make something easy enough but how effective would it be, who knows.
All v8 throttle bodies have the same bore size, the 302/351 are identical, the 460 has extra issues that need to be addressed to fit, so go with the SBF TB. It will bolt right up with minor linkage issues to be addressed. You also have to port match your intake, more involved.
Im not sure Id tackle it for performance, as there have been guys modify carbd engines using a one barrell carb and theyd flat haul ***...so the stock TB which i believe flows 400 or so cfm, should be plenty for a hot street engine.
If you believe SS dyno experimentation, he suggested there was no vacuum at WOT on his engine, which is an old trick carbd folks used to see if they needed more carb, if vacuum is present then you need an opening that will flow more cfm, his did not.
You could read the thread right around this one titled "optis attempt at a larger throttle body".

Don't worry about larger TB's if you haven't done any work on the head to improve air flow. The stock TB flows better than the stock unmodified head does.

There is some debate as to how well the filter, filters...
with that said, I paid a whopping $20 for my K&N replacement filter, far as Im concerned it paid for itself vs cleaning it/oiling vs paper filter scheduled replacement but now I think they are $30, so who knows...

Paid $50 for mine.. and I have to oil it. When it's time to oil it, I'm just going to replace it with a paper one. I honestly don't think it does any better than a cheapy one.
