@saxbros It would definitely move the exhaust out alot better. That plus an intake, cam and 2bbl carb, she would run like a scolded dog
-
could you tell a difference in power with the efi manifolds?

Sounds very good

i got a 83 f-150 w/ 302 and i pulled the belt on the air pump but i wasnt sure if about pulling the hoses off of it. how do you tell whats smog and what can come off and what needs to stay? any help appreciated.
-
did that on my 86' stepside, it runs great, hell even better but the check engine light is on (naturally), i had to switch back to earlier year carb to take all that smog shit off too haha
-

haha ok, that is sumtin new, but i dont get it, i looked throuh all the conversation, i dont get why it pops like that more like a v8 then purrs like a 6 banger, u said i t has no cam which would be my first guess, and doesnt look like a ll that much of power adding was done, just what u od to make it sound like it? is it literally just true dual straight pipe from the headers back? what u doing for exhaust? sounds nice man

Just true duals. The truck had 78,000 miles on it. The "log" exhaust manifold cracked, so I changed it out for the manifolds of a '91 with EFI. That allowed me to add two downpipes. Those just go straight back through two pro-flo turbos. Each bank of cylinders has it's own muffler. The reason is pops like that is because there is no cross-over pipe in the system to even out the sound pressures between the cylinders.

ah thats terrible to see a 300 with all that preformace killing emissions shit glued to it the true 300 6's were bare bones

None of the emissions stuff is active. Notice I removed the airpump. Everything else (ERG valve, etc) are blanked off to create a smooth plenum from the carb to the intake. They are simply there to "look good" to pass emissions. So don't worry, the truck has all the bare bones power a 300 should have.
