340 camshaft

Great suggestion, and wise advice (learned the hard way - like most of us...)
Two additional suggestions
CC the heads while its apart. There's no reason to guess what the compression will be. I will never have an engine together again without knowing the actual head CC and piston above or below deck.
Stock heads aren't going to flow significantly more with the valves over .5" open.

I've used the street dominator intake and found it pretty decent single plane at lower rpms. It had a better rep than the Torker but I've not run them back to back. If you want to stay with single plane, I would try both. The Eddy RPM with a Holley 4150/60 will bring the air cleaner close to the hood. Check and double check clearance of stud and lid with clay or aluminum foil. A mild drop base will likely be needed.

Thanks, Mattax. Points well taken. I'll add this regarding lower dual plane alternatives, as well.

If a Performer RPM intake is too high to fit underhood, there are quite a few good flowing intakes here......

Everything from OEM cast-iron intakes to various aftermarket types. There are even a couple of hard to find and exorbitantly priced LD340 intakes.

Performance wise, the lower priced sleeper would be the '71 AVS intake (run your Holley on it)......

The 1969 NOS Weiand intake is not cheap, but performance wise, its the equal of the much sought after LD340. And the seller is taking offers, so you can likely get it for less than the 'Buy it now' price.

This intake is the real deal...... Not what is sold under that brand name now of days......

Don't waste your time on the lower profile Performer spread bore intake. The OEM iron AVS intake will outperform it and the vintage Weiand intake will run circles around it.

Hope this helps,
