Aluminum Intakes - What are You Running?

It may be hard to believe, but the stealth is a near direct copy of an LD4B. Not mentioned here is a 1971/72 iron 340 intake. Probably as good or better than as most of the smaller aftermarket intakes you’ll bolt onto a 360. I guess it depends on carburetor, too. Spreadbore, the iron 340 or a port matched Edelbrock regular performer (ports deep matched from 318 to 360 size) to are both very good. The port matched performer is a smidge better on top end. At the level you’re talking about building, a Performer RPM will still work the best of all. You’ll actually notice a difference over the other manifolds. Unless you have an LD340 just lying around, then use it.
