428 Street Car Cast Iron Exhaust manifolds -

[PANAVIA]

Ok originality dudes. -- where did the cast iron FE manifolds come from on the CSX 3300 series of cars >?

1966 Galaxie

[PANAVIA]

hate to tell you ZO- but nope. that is not correct.

- it may have been a custom add, but after reviewing CSX3357 in person, i can tell you they are not from a galaxie.

Pictures to follow.

Some trucks have the same manifold on one side, exit angle is wrong on the other.

[mr bruce]

The one side is a stock FoMoCo part, the other is custom, don't know if they were custom cast or welded, hard to tell from the 1965 proof pictures I have. Unfortunatly the pictures I have are copywrited, and I am prohibited from posting them. I can have new exact manifolds cast, but I doubt folks are going to want to pay the price.

[mickmate]

The real price is horsepower, they rob about 100 from ya. That would be why I'm making tri Y's right now.

[Rick Parker]

Is this a multiple choice question?

[Rick Parker]

How about those on a 260 or 289, now Those were funky!

[mickmate]

Ah yes the cast tri-y Mike McCluskey is reproducing those.

[PANAVIA]

ok, here is CSX 3357 . . .


and the casting number



no where did these come from >? the Ford Combine industry >?

[mr bruce]

Ford industial motors, water pumps, drill riggs, etc

[saltshaker]

did anyone figure out where the manifolds came from?

[Ron61]

I am not sure where the ones on my 1969 Cobra 428 SCJ came from but they are nothing like the pictures shown. They have runners that go into the main section and exit at the back. The drivers side had to be cast to clear the steering collum, so I lost about 50 horsepower there. When the engine was out it was ran with tube headers and the stock ones on the dyno and with the tube headers it was right at 500 horse and with the stock cast ones it was right around 450. I kept the stock ones so I wouldn't have to cut the shock towers to get the tube headers in there and I wanted to keep the original look.

The only difference right to left is the right hand manifold is drilled and tapped for the choke heat riser, they have the same part number. I believe the apparently anodized part shown in the picture may be incorrect because the original heat riser fitting was steel. This is in relation to the cast log manifolds.
I did see a very early narrow hip car in 1966 that had a fabricated shorty tube header from Shelby American. I was told that they went to the log manifold to reduce costs on regular production street cars.

So, we still don't have an answer do we?

[PANAVIA]

nope-- still an mystrerererrreeee
