bonus from my parts truck

[72hiboy4x4]

after many (many) months of messing around, I finally got the 390 engine pulled from my '65 parts truck.
well I know it had a holley carb on it, but when I pulled the air cleaner off, it turned out to be a 4BBL carb, and after I looked it over, the intake is an 'S' code manifold!
so I'm a happy camper now. and I want to send a special thanks to DarrelM and his friend for donating this truck to my project!


on a side note, I found a '80 F-250 4x4 that just needs one of the engines I have laying around here for CHEEP! supposed nice body and interior, complete minus engine. and I already have an '80 for parts here! can't beat that with a stick! I'll see it tomorrow and get pics if I get it.

i love making good deals like that work

Okay.. not into the whole FE thing.. signifcance of the "S" code manifold?

I am interested as well...I may look into my Intake in further detail



^ Where would the code be found

[68F250]

Lots of folklore on the 4V "S" intakes. There are several versions of it, early S, later S, big S, little S...
Personally I think the early big S is the better one.

Guess we'll find out with the network54 intake tests.

Here you go. Badgt04

[mrsnicks]

Umm.. but what does the S signify? What makes is so Special?

Patrick

[Badgt04]

rjewkes, so it is an S-code intake that I have?


Does this mean I can retire at the age of 19 ? !!!!

Hi Fellas,

The S intake is associated with the S Code engine in 67-69 Mustangs and Cougars and other Fords / Mercurys (earlier for these). Next to the 428, it is a big deal in the Mustang / Cougar crowd because it is a big block. The S Code engine was a 390 cid 4V rated at about 320HP. The S Code engine is also referred to as a 390GT. A Holley was used for carburetion until 1969 when an Autolite carb was used.

4V S intakes were used on more than just the S code engines, also used on the 410 and 428. I don't think the S on the intake means the same as the S for the engine code or that the two go together. There were many S code engines with T intakes.

Hi Barry,

Agree that S intakes may have been used in other applications. Never said that the intake was only used in a certain application.

Was only trying to point out the general association that many folks make, whether right or wrong, concerning the S intake.

Hi Jim, I wasn't trying to be argumentative. Sometimes it's hard to write the tone of voice.

More info, there were also 2V S and T intakes.

Have heard that the first S intakes were designed for the Tbird but then used across the board. I don't put much faith in that, just spreading the word.

[rjewkes]

doesn't it have something to do with the runners? When it comes to an intake. On the engine does this signify HIPO?

[68F250]

Yes, the runners on the T intake are like the old '58-'65 design except they neck down to match the smaller head ports that were standard on most '66 and later heads. The runners on the S are more uniform, does not signify HIPO. Here's a pic of a mid '70's T (with EGR) and a mid '60's S for comparison. They both have the same size ports at the head flange.
