In another thread, I asked about swapping intakes in the Power Wagon to gain some more power. I got the truck with a 440, 4 speed 4wd and 4.10 gears. The engine has an SP2P intake, ThermoQuad carb, stock exhaust manifolds and a 2 1/4" exhaust system. The engine has about 100,000 miles on it and runs smoothe with no smoke.
The truck falls on its face above 3000-3500 rpms. I'm certain that this SP2P is to blame, and I have 2 intakes on the shelf here that I can try. I asked previously about the "Performer" that I have, but I recently acquired a "Streetmaster 440" intake as well. The Performer is a dual plane while the SM is a single. My thoughts are that the dual plane would be a better choice because they are designed for low to mid range operation. Opinions?
I have a pair of 1 3/4" headers that I may use on the truck too.

Fb ....works FINE on that MH in the avatar pic ! .... but when I go with a muchO shorter gear(from a 4.56 to a 3.73) ...I will use the SP2P .....

Performer all the way. Streetmaster was a half-baked idea that came out of the same mental malfunction as the sp2p. Sort of a mash-up that instead of combining the best of two ideas combined the worst of the two.

Its about 1 step better than a small block SP2P intake and thats not saying much. Its best used as "Wall Art" or for aluminimum scrap..

I guess that I have come across some "free" stuff that was certainly worth what I paid for it! The body lift kit, the SP2P and now this intake!

IMHO,you will not know of any results if you do not try it.

I do stuff all the time. results vary.

everyone told me the small port LD4B would not work out good on a 360headed 318. it was night and day over the performer. as a matter of fact,it works better on my 360 headed 318 than it does on the #302 headed 318 with the same roller cam back to back.

would it do that on a 360?? maybe not. but I would try it before knocking it. I only knock what did not work for me. like the sp2p, I have never ran a street master.

I put a holley street dom low rise open plane on a stock 2-v cam 318/small heads and it was a screamer with a q-jet in an A-body.

put it on my 360 with 292/292 lunati bracket cam and it works great but you can tell it is holding it back. but thats a 3/4 ton 8 lug 4.10 gear long bed truck.

swap my weiand action plus on the 440 for a RPM intake with a 600 eddy carb. 3.91sg

just put the q-jet/3.23 gear on it and picked it up from a flat 10 mpg to 13 mpg and still has some

I have a weiand 360* intake that is open plane with a divider down the middle and it is low rise with almost no runners for a squarebore carb. if nothing else a good weekend T&T to know if it works or is truly shelf art for the shed.

same with the wieand single carb tunnel ram i picked up. either it works or it is nice shelf art for the shed.

if you are not into 'testing' it,then you still cant beat free. dont you have a mancave or shed to put it in?

I have a stock intake that will most likly out do either of the ones you have if you want it. scratch up a thermobog or a qaudrajunk for it.

you are more than welcome to try the offy intake or the t-ram if you want to.

if not I will take both off of your hands to go on the shelf in my shed with the rest of my art work holding my carbs up off the shelf.

you could have already swaped it and know if it was an improvment or not.

I will wager it is a little better than the sp2p but you should be looking for a street dom or RPM intake. IMHO.

and a big plus is you have no TV linkage to fuss with.

I like the ThermoQuads for the economy, so I'll stick with the spreadbore design. The standard Edelbrock Performer has this so I'll likely use it. The truck has inop A/C. Later when I install the intake, I'm going to ditch the A/C pump and change over to the non- A/C pulley arrangement. I got this truck to replace a '74 2wd Camper 9000 that has all the parts that I need.
Ultimately, the goal is to make this truck into a red/black Macho Power wagon clone.
I am quite interested in making these parts either swap meet sales or wall art for the garage. I remember going to Auto Speed Shops and seeing parts hanging on the wall, thinking of how cool that used to be.

My first intake was a new Weiand 7504 for my '68 chevelle 350. The carb on top of it was a Holley 6619. Remember those? Turn the screw IN to richen the idle.
Somewhere I have my copies of the Hot Rods and PHRs from those horrible days of gasoline shortages and homemade V4s.
So I remember the SP2P when it was new and the Streetmaster which was a single plane that they tried to get to run like a dual-plane by choking down the plenum and downsizing the runners.

A 205hp Corvette was a big thing.

It is a sign of the times that Edelbrock dropped those and went back to a classic two-plane design which they called the Performer.
You can get a duck to walk on soft snow by fitting snowshoes, but it won't work very well. you can get one of those misfits to work if you are satisfied with a 165 hp 440.

Double D .... the Streetmaster was no "duck" ... I have used that on my MH(413) recently with very good results. ALSO talked to a guy who is running a BBC boat ... tried the SM .. loved it.

Eddy went to the "Performer" TO SELL more intakes .... that intake is not much better than a decent OEM iron one. Now the Prpm is a diff story.

165 HP 440 ? ... my 413 will DO THAT on the front TWO BARRELS of my ThermoQuad .... now maybe with YOUR TUNEUP 165 is all you can get....

It's clear that we don't agree on this. My reference to 165 hp 440s was to the SP2P.
Sounds like what you REALLY need is an S.P.2.P-2V . Ever seen one of those?

R.

THAT is clear

All I am relaying is my personal experience ..... MOST EVERYTHING talked-about-here is HP .... NEITHER of these intakes are that but they are good(in my experience) for better throttle response and mpg. Again .... I am running the SM on that MH .... things are fine with the 4.56 gear .. but when I go to the 3.73 ...I will be putting on the SP2P..... since RPMing the motor will be lessened by that swap.

The 2V SP2P ? ...I have seen that for the SBC and HEARD that there was one for the SBM and Ford .... but that is it. I would NOT want one of those for the BBM .... because any 2 bbl carbs I know of are not-the-plan for any decent MPG..... PLUS you need 4 bbls at times with towing.

And AGAIN .... don't junk any of these intakes for scrap-aluminum ...sell them to ME

How about 4 boxes of FRESH FrankenBERRI cereal ?

Uhhhh.....
Swap meet it is.

Hey Doc.. Looks like you screwed the pooch on that one..

Nah SHORTstuff .... I still have a few IN STOCK

Fberri .. that offer was a ... give me a counter ...

I sea you lurking .. mgoBuckeyes !
