Best intake replacement
My son has a stock 64 with a 300HP engine.
For Christmas he wants a cam and intake. I am going to get him the 151 GM cam.
I looked for the correct aluminum intake either from the 64-65 or 66-67.
But the price is prohibitive.
What intake/carb do you guys recommend?
I was thinking the Edelbrock 2701 low rise Performer.
Thanks

Intake and cam
The '151' would be a pretty good choice if he is set on swapping the cam, but I would install it advanced 4 degrees for some more low end torque. It does tend to like more compression than the stock 300 HP engine has. I've never used one, but Comp Cams offers their retro series 300 hp cam if that is of interest. The stock 300 HP cars run very well as is. If his '64 uses an oil fill tube in front of the intake, you'll need to have that hole machined into the new aftermarket intake. I've only seen the Edelbrock intakes with that boss area still cast into them.

I replaced my intake & carb, w/the edelbrock EPS intake and 650 thunder series carb. Couldn't be happier. For an extra $100 you should get the endura shine finish looks like chrome.

Didn't 300 hp '64's come with an IRON intake? If so a hi-po, hi-$ GM intake would be incorrect.
If my memory is correct you might as well go with the Edelbrock. Much has been learned and applied about intake breathing in the last four decades and a Performer manifold would improve performance from idle to redline. They can recommend a hydraulic cam to match your son's carb, intake valves and, I presume, stock exhaust.
If you want it to look stock, grind off the Edelbrock script, sandblast and paint or powder-coat Chevy Orange!

Check out Classic Camaro for a GM dual plane intake, good intakes .
PS you had the right idea, use the 151 cam

If you can find one used on ebay, the C3B is a good aluminum intake for the SBC. If I remember correctly, the AFB will fit on the C3B. I believe the 7101 is the old C3B but not 100% sure.

The High Performance 365hp came with the Aluminum intake a Holley carb.

try this link to the archives. You may want to think about using the 2101, to clear the hood and to be able to add the oil filler tube with a pcv fitting. Problem is, its really spread bore carb manifold.

I have the 151 cam in my 61 2 x 4 283 and it runs and sounds great. Now my son wants the same thing.
I would like to use the original AFB if possible.
He has a 65 big block hood on it, so I don't think there will be a clearance problem.
I don't want to use a Holley.
He has a cast iron manifold on it now, but I want to put an aluminum intake on it so it will be stronger.
JoeC5, is the C3B an Edelbrock?

There is a C3B and a C4B I believe. The C3B has an interesting race history designed for the holley 3 barrel and has a large notch in the plenum to clear the large butterfly. You can find these old manifolds on Ebay pretty cheap. I'd opt for an Edelbrock RPM or the EPS and have the oil fill tube hole machined since he has a BB hood on it.

C3BX - Most do not have the milled center divider. Most are drilled for both standard square bore carb bolt patterns (AFB & Holley).
The C4B is reported to extend performance a little higher in rpm range (beyond 5500 rpm with a 350).
Each of these manifolds are displacement sensitive, the rpm range is extended for a 283, compared to it's performance potential in a 383.
FWIW, the ports of a C3BX appear larger than a more modern 2101 (comparing the manifolds on my spares shelf).

You may be in luck with this C3B, I have the same one on my car.

Good Luck !

I don't mean to argue with you. And it's your car, and you should do what you want. And different people have different tastes.
But the price of an original aluminum (AL) '64 intake over the price of an aftermarket is not "prohibitive." The price delta of the original over the aftermarket is perhaps $200. Some people in this hobby spend that on wax or NOS air for their tires.
If you have a 300 HP engine, and you're looking for a cam, intake, and carb, you're looking for a performance increase and a prettier looking engine. I don't know about the performance part. But I can tell you about the appearance part, because I did this myself. (I've since gone back to stock.)
An original AL intake will look nicer than an aftermarket one. A stock part will also increase the value of the car more than an aftermarket one. With an original, you won't have to have it machined for the oil fill. There's also a machining expense if you choose to have the "Edelbrock" or other script machined off.
If you make this change, what are you going to do about the oil fill? Valve covers? PCV system? Air cleaner? Gas intake line? Choke? There isn't much room under the stock hood.
If you do go with an aftermarket intake, try to use your existing carburetor. If it's the stock AFB, it's better than any aftermarket carb, and you won't need to solve air cleaner, gas line, and choke interface problems. And you'll save $300.

Going with an original 365HP intake isn't going to make the car into a 365HP car. The engine pad suffix # won't match for one, the hyd lifters with the 151 cam won't sound like the solid lifters in the 365. And, the 350HP engine wasn't an option in 1964. What's the point of faking a 350HP engine with all original parts, and at a higher expense, when it wasn't an option in '64? If you go with a C3B like Crazyhorse has for sale, you can use the original AFB that's used on the 300HP and also retain the original air cleaner. Having Edelbrock cast on the intake isn't going to make any difference. Keep the original intake, in order to change back to original in the future.

Better yet if you are faking it anyway (I have actually done this to a 64 and it works great), just put in the 151 cam, have the bigger valves (2.02/1.60) correctly installed in the heads and finally, use the 300 hp manifold (port matched) and the stock AFB. It was a real nice running motor, that looked completely stock from the outside..

Installed the Edelbrock Performer Intake and matching carb ('65 350hp)... response was instantly more crisp
Very happy with the setup... as said before, the intake manifold does cover up the stock oil fill, so you will need to get valve covers with oil fill & pvc.
