I have a 57 Chevy with a 283 and an aluminum snowflake intake stamped GM 3823481 - google comes up with some varied results, hoping someone here would know.

Also, bell housing 8640320?

Although my Corvette Black Book doesn't show it, it must be a 1962-1967 Corvette Intake. If 1962 or 63, it will have the Carter AFB bolt pattern. Since you have it on a 283, my guess is that it is one of these, from a 327/340 hp engine. 1964-67 will be drilled for the Holley with a slightly larger bolt pattern.
Hope this helps.

I have a 283 FC code matching numbers I believe, so it was a 283 with 4BC and powerglide. It has a 4B Rochester that is also of the correct vintage.

283's didn't come with aluminum single four barrell intakes in any year, to the best of my knowledge. Only aluminum for them was F.I. or 2X4 intakes. Also the number 3823431 is far later production number than 1957. These are the reasons that lead me to believe it is a '62-'63 unit.
1. Since that is the first year of aluminum single four barrell intake production, and
2. The numbers are correct for these approximate years...again to the best of my knowledge.
Hope it helps.

The Corvette did not have a Rochester in any year, just Carters and then Holleys. And the Corvette with aluminum intake would have been an AFB or later a Holley. Have you had it off- I think the casting date is on the bottom on the aluminum intakes.

Don,
Correct. He has a 283/220 from a passenger car, I'd guess, where the Rochester 4 bbl. was the std. carb. Clearly somebody has been swapping parts on the car. I was unaware of a date stamp. Good info!

Joe, there is one on ebay for a 63 340HP that has great pictures of the whole intake, top and bottom. It is not the 3823481 intake, but it has great pics.
( http://cgi.ebay.com/ebaymotors/63-Corvett e-340-HP-... )

Would an aluminum intake have had a Rochester or a WCFB (unless it was a qjet)? Or would they be using an adapter to mount the Rochester on the aluminum intake?

I'm still learning this stuff and find it quite interesting some of the weird things GM did that make little sense.

Don,
The '62-'63 aluminum intake would mount only a Carter AFB without an adaptor. The WCFB has the same small base as the old Rochester 4 bbl, smaller than the AFB or Holley. I don't even recall an aftermarket aluminum intake that the WCFB would bolt to except, of course, the 2x4 units. Wish we had a picture of it.
With the ebay '63 date stamped intake having a 379xxx number, one would think that the unit in question (382xxx) would have to be newer, by a few years.....That would have to make it a Holley unit from '64-'67.

Sorry for the delay - Here are some pics I took before I detailed the engine.

Photo helps, but everything isn't visable. Looks like an adaptor under that carburetor to me. Also an adaptor on top of the carb to fit the larger Holley/AFB carb top air cleaner to the Richester. True? If so, that would make us pretty much correct in our assesment of your intake. Sorry I can't ID it closer than that. My best guess is a 1964 model, but only removing it and flipping it over will verify that date. If you decide to do it, please post the results for all to see!

This intake is a marine intake. I have one. Someone replaced the cast iron original one.

And that is EXACTLY what I'm wondering.
I cannot find that casting number in ANY Chevrolet reference book.
The casting number puts it in the 1963-64 time frame

I have one of those intake manifolds also; # 3823481. Except for a couple of minor differences, they are an exact copy of the cast iron, WCFB/Rochester 4 jet intake manifolds. They have a small boss, right to the passenger side of the thermostat housing area that's drilled and tapped for two 3/8 course bolts, for an unknown bracket mounting. There are also four access bungs into the runners, two on each side, and what they're for, who knows? Mine has the date 8-21-63 cast underneath. The under-the-carburetor heat transfer is heavily etched on mine (NOT the heat crossover from head-to-head). I paid $80.00 for mine, and of course, the guy told me it was "from a Corvette"; I knew differently. They were used on BOATS, although some guys claim they were used on tank engines. Despite being made of aluminum, it's actually fairly heavy, at least-wise heavier than my early 56 dual quad intake, and a couple of aftermarket, single 4 barrel intakes I have. I wish I could post images. I am Butch/56sedandelivery.
