Friend of mine has a 62 Chevy Impala with a 327 two borough. He's having trouble with his two barrel staying running at a stop sign. I have several small block Chevy aluminum intakes and a 600 Holley carburetors. My question:

Can I use a standard small block Chevy dual plane aluminum intake on his 327 without any problems?

Yes, as long as your donor SBC intakes are not the Vortec bolt angle/pattern. Also, as @ChevelleFan70 mentioned, the only caveat is if your manifold is void of the 327 oil fill tube, he'll need provisions in the valve covers for oil fill. If I remember correctly, my factory 327 covers did not have any holes.

In 1962 GM did not offer the 327 with a 2 barrel carb (in their full-size cars). So, either something was changed; or it's a 283. The 283 had 2 barrel carb w/single exhaust.

The 250 hp 327 had a 4 barrel carb and 2" dual exhaust manifolds/pipes; the 300 hp had 'larger' aluminum 4 barrel; 2 1/2" exhaust manifold and pipes. No single exhaust for the 327.

Before swapping manifolds, you may wish to verify displacement.

none at all, but a 600cfm may be a little much for it. Be prepared for tuning.

Tuning; cylinder heads (esp with 600 cam carb), cam; exhaust; all will need study/attention if not replacement. The 283 from the 1962 full size chevy was max 170 hp at about 4k rpm.

None of that will need to even be looked at or replaced. Unless it is in poor condition. With that being said, a 600 is a little big and will need tuning. I personally would opt for a 390-450 cfm holley.
This swap has been done thousands of times with no other changes

Or I would just rebuild the stock 2 barrel, SUPER EASY (unless its cracked or warped or just totally worn out)

In all honesty, he might just need a good tune up. It looks pretty clean.
Have you checked the plugs?
checked timing?
checked cap and rotor?
Points and condensor?
done any adjusting to the carb?

It does kinda look like an hei dostributor, but I cant tell from the pix.

I would try a basic tune up first, unless you guys are dead set on putting on a 4 barrel.

Also, check casting number on back of engine and numbers on front pad. Lets see what this engine really is. It may not be the OEM engine after 60 years.

Like all of the others have said you need to get an intake that has the provision for the oil fill tube or change the valve covers.

I have to agree with the best bet being to rebuild the present carb and not have to mess with anything else.

So in the pics, I see valve covers with breathers where oil could be added. Oil tube is a non-issue.

As others have said, prob worth checking the casting numbers/engine code to know if you have a 283 or 327 before you dig into it.

It could be a 327, as the 250hp 327 did have power pack heads and a 2bbl on it in the old days. Find the block numbers and someone can figure it out for you.

Probably has a points distributor, how are the points, wires, plugs etc?

I agree with the tune up first then rebuild the 2 barrel. If he is looking to run the Holley 4-barrel any dual plane intake will fit and as already said he will need to add oil through the valve cover.

I'm thinking HEI. There is no external coil that I can see.
