Intake manifold questions

[33IMP]

Imo, the best use for ANY streetmaster, is lining a trash can to keep it from blowing away in the wind.

You could always find a first generation Torquer intake and port it like the “Ugly Torquer” I did for my son. Lol

 

[rumblefish360]

Which is better down low, the Streetmaster or the SP2P318?

FWIW, the SP2P 318 was designed for mileage during the gas crunch era. They came in a 2 & 4bbl configuration.

huh TIL. i didn't know that they came in a 2bbl version.

SP2P - Most people don’t believe it came in a 4bbl version.

The other intake is only a 4bbl.

 

[junkyardhero]

yeah, i'm aware of the street master only being 4bbl.

the SP2P as a 2bbl doesn't shock me, but in all these years i've never seen one in the flesh.

 

[volaredon]

The last 2bbl sp-2p I saw was at a swap meet and actually for a big block, didn't ask, didn't care since that's not what I have.
The sp-2p I had was a 4bbl small block version

[Newbomb Turk]

I would not use that.

FACT^^^^^^^^^^^^^^^^^^^^

I didn't know it either.

I've seen ONE in person for a Chevy small block.

is it the angle or the position of the shot or does the carb mount angle forward kinda like on a marine motor? that's wild. man... i'd forgotten how tiny those ports are!

I thought that was a feature on just about all intake manifolds to make up for the backwards tilt of the engine and transmission to achieve proper drive line angles.

I really don’t know, you got me there.

are they and i just never paid attention? or maybe it's something in my lizard brain that just ticks the box and stamps "QC OK" because it's logically supposed to be that way...

Just saw this on Facebook

A good price on that LD4B intake. The ad says the manifold bolt holes were elongated for an earlier 273

If it was all I had to choose from is it or a Chinese made manifold, I would take this one in a heartbeat.

I’ve never seen a Chinese W2 intake yet. Probably never will

 

[jeff alder]

LD4B if you can find one. 1500-5000+ rpm range

There were 4 of them at Indy. I should have bought them all and passed them along. I thought about it. I saw one auction on ebay for around 500.oo. One at Indy just needed a little refurb for $150.00.

I was able to find out more info on this manifold. Was basically a small carb manifold designed for mpg gains on stock smog engines of the 70's it seems. Not the bargain I had hoped it was. I did not buy it once I found out what it actually was. Thanks guys.

There is no EGR valve on it, not California smog.

 

[Swinger 340]

The street dominator is what I run on my 340, in my van. The main reason I bought it back in the 70's is for the clearance in the dog house.

If you want a really good old school intake, find a Street Dominator. Also a single plane, but they lose nothing on the bottom end. They have a full, open plenum and not the funnel crap of the Streetmaster. Still available reasonably.
