Since I've got MoPar s.b. in my -55 sedan this might not fit here...?

1: Does anybody know about alu intakes for 318 engines?
(I want it as low as possible!)
2: & do I loose or gain torque with a low manifold compared to a higher one?
3: what might be the best/cheapest(low-priced, not badly made) brand?

Any thoughts?

Oh yeah, there's also the question if anybody has one "laying around" for sale... ;)

Which series 318 do you have, early or later. Doofus

It's from -89, from a van we drove a lot.

Check out all of the normal sites like Summit, Speedway, Jegs, Rock Auto. I would think that they would be fairly common.

Nox you have the late or LA series engine,273,318,340 360. there was an odd factory 180 deg 2 bbl manifold around '78 that was really low. it was on trucks. after market is probably your best bet. seems like '64 was the early/ late break point but not set in stone. avoid "Hi Rise" style, stick with factory style if possible.

When I just got the donor car (-77 Volare wagon) I read all that, got me confused & for a while thinking that maby it was a 360 since it said the 318 only came with 2-barrel that year & my Dutch sold had 4-barrel.
But then there was more changes, I was used to Swedish sold cars who had 15 inch wheels & happy about that & the donor car had 14 inches, not so happy about that...

Anyway, Jeff is helping me to get a good manifold now!

If You can find one, the 2 barrel manifold from the 1964-1967 273 was "state of the art" at the time, may be a version of the one doofus alluded to, trucks had some different parts than cars at times.
I put one on a 73 318 pickup and got better performance and economy. Just saying. Particulars are that the intake manifold was a hybrid single/dual plane design that used one plenum for each side of the engine, joined by a carefully sized rectangular passage that solved lean/rich problems that had occurred with the original “purely” dual plenum design that had dedicated one barrel of the Carter BBD two-barrel carburetor to each bank. This reduced the height of the engine and allowed installation in the Valiant. Same thing would apply to Stude hood.

Things takes time & stuff gets in the way... but I discovered the timing chain was waisted, no miss firing but really slack & here's the thing: When I did my original -77 318 some years ago it had a chain tensioner but the -89 don't & when googeling I found out that only magnum V8 & V6 has it original.
That got me wondering if Studebaker V8 has/had it?
(This is mine this evening:)
Just wondering...66025

No, a Studebaker would not need a Tensioner, since there ARE NO Timing Chains or Sprockets! :rolleyes:
