340 intake upgrade

[70swing]

I'm thinking about switching to a RPM airgap intake manifold. My question is will it out perform
my stock 70 340 cast intake. 3462848 casting number. Any opinions?

It should, what carb are you going with

I'm running an Edelbrock 650 Thunder Series. Mild cam and headers.

Either a Air Gap or LD 340 would be an upgrade over stock.

OEM intake is not included, but here is an old test that may help in your choice. Pick the best numbers within YOUR usual rpm range. Probably the RPM Air Gap, or even the "regular" RPM that's not listed.

Yes, it will perform better than stock. I run an RPM air gap as well because I wanted a dual plane intake for street and strip. It's a fine intake and I have had zero issues. Get one.

Thanks for the input. Airgap it is!

from that article it would indicate a 325 - 350 hp engine would perform about the same with any intake.
