440s are easy for intake swaps too. I know that the Performer isn't as performance oriented as the RPM version, but it IS a truck. Low to mid range is where I need the power.
I agree the performer is better than the sp2p intake.
I just put an rpm intake with a q-jet on my stock 440. picked it up from 10 mpg to 13 mpg with a lot better throttle responce and torque.
takes about 20 mins to swap my intake start to finish on the 440,cant do that on my 318 thats for sure.
another good thing on the granny tranny or any stick shift... you wont need the TP valve lionkage which makes carb selection and hook up that much ez-er with a tall intake.

Couldn't have said it better!
I bought a new manifold and Holley Economaster carb for my 318 back in the gas shortage days, and the truck couldn't get out of its own way. I got about 2mpg better than the stock setup.
I now have a Performer cam, manifold and carb, and get better mileage than the SP2P, with a huge increase in performance.

Well ..to the who say REcycle ? ...send them here !! But they do run out of steam at about 4200 or so ... but on a truck or MH ....why would you need more r's than that? To the OP (FRANKENberri} ... I would suggest a Streetmaster. THAT will go to 5200 or so.

MY POINT: You don't have to lie to people. There are 35 Performers for sale for every SP2P. That makes them rare. They were designed for maximum fuel economy. Now maybe it's your opinion that they don't work, but that's what they were DESIGNED for. So it's a rare intake manifold designed for fuel economy. There isn't a lie in that sentence. There are actually s ome folks out there who are looking for the "ultimate" fuel economy intake and they may think that the SP2P is the Holy Grail. Now it isn't lying if you don't tell them they're wrong, everyone has the right to his own opinion, after all. I've seen them sell on the 'bay for $70 - $90 if they were presented right. That's a lot more than scrap, $15 or so. So clean them up and get them out of your garages. Shoot, the Model 4360 Holley 450s are going for $50 and up used but clean! Two years ago I bought two of them for $35 or so each, brand new in the box. People go nuts when the price of gas goes up. R.

it is not RARE! it is VINTAGE! that is no LIE! I am swaping mine around in a quest for more mpg on the 440 truck, but as it is now with the rpm intake/NOS edelbrock #1905 q-jet/thermobog replacment carb for 72-85 dodge trucks with 360/400/440 engines. then swaping from 3.91 to 3.23 gear got me from a flat 10 mpg to 13.7 mpg. plus the HP/Torque the rpm intake has, the kick of a spredbore carb, with truck weight down to 3700# a 2.76 gear should improve it even more on the highway. the 440 will have enuff low end torque and spin 1850rpm at 60 mph. the stock 77 MH 440 cam seems to have the sweet spot at 2000 rpm for cuzing/mpg then pop the 3.91 back in and wont even have to retune the engine. just
