Alum.intake for 82 ?

[zgator]

I posted eariler about the 82CE I'm going to buy.This CE is stock except for a 21/2" stainless true dual exhaust and a preformance chip.The owner has a alum.crossfire intake that goes with the car.He never got around to installing it.My ? will I get enough of a gain in torque and or hp.by going through all the trouble of putting it on?I've been up to my neck in muscle cars going back to the late 60's and have done all kinds of engine mods.but I haven't dug into anything this new.(if you can call an 82 new)If figure there has to be all kinds of stuff to R&R on this intake and I don't know if it will be worth it.I can always put it on e-bay!!!.

The stock '82 is supposed to have a crossfire intake with 2 throttle bodies on it. What is on the car now?

The car has the factory stock intake on it now.He bought a aftermarket alum. version of the stock crossfire.I think he said it was an Edlelbrock preformance one.Said it cost almost $800.00..I can beleive that because GM only had that type of setup for two yrs.Really wouldn't be a high volume piece. :confused

I don't think you will like a 2-4 set up on the stock '82 engine. I would leave it alone;sell the intake. This is just my opinion.
Good luck -

The stock 82 intake manifold *is* an aluminum "cross-ram" which mounts two single-barrel throttle body injectors.

Edelbrock does not make an aftermarket, a high-performance replacement version of the stock 82 intake, however, many years ago Edelbrock did make a dual four-barrel carburetor, "low" (ie: they have a plenum) cross-ram for small-blocks as did Chevrolet, but those intakes were designed for race cars, especially, the old SCCA Trans-Am series of the late 1960s. While one of those manifolds might fit the 82, an L83 engine with two four barrels on a racing cross ram would not run very well, if at all.

If the guy wants the deal, tell him to keep the intake and knock 800 bucks off the price of the car.

Sounds like you have an aluminium edelbrock crossram, most likely an STR-10, it should say that somewhere on the manifold, or it could be an SY-1, the Smokey Ram.

Both are NOT bolt on items and they will only work properly on an engine with more cubes (383, 400+...), a good cam and some decent heads (as in NOT the stock heads)

The original crossfire manifolds that I have both have a big "W" logo on them. It looks like the WEIAND logo. Did they make them for the stock L83?
Has anyone tried machining the runners completely off the inside of the manifold and fabricating and welding new tubular runners to improve the flow on these? There's lots of empty space inside there that could be used for flow improvement. And I have heard the "sobotage" story regarding the manifolds from some of the guys that built the throttle bodies at Rochester Products division. Even with manifold improvements it seems that the valves are too small to get much more from the L83.

Thanks.

The snowflake with the W in it is the Winters foundry logo, they did a lot of GM casting work

I have an intake from a '64/'65 327/365 HP Corvette (casting/part #3844461) that has the 'Winters' stamp on it, and I'm told they (Winters) did work for GM well-before that date, too.

Yes, Winters foundry cast many GM aluminium parts
