LD340 v Airgap

Do yourself a favor and make just one thread or you’ll be jumping back and forth between threads. It tends to a bit convoluted when there’s multiple threads on the same question in different sections.

A copy and paste from the other thread;

From what I remember, there was a small gain not worth the price. A few fellas called up Edelbrock and asked about this very thing. According to what they were told, it wasn’t really worth swapping. But there is a gain. One of the things to consider if you’re thinking about this is the intake remains a little cooler.
Eventually, all intakes get soaked with heat. The RPM-AG is a little less.

I have run both. My LD-340 was modified via the MP book’s instructions. A milled divider and opened up to use a TQ. It was a very power intake. When the TQ was at WOT, it was a screamer. Between the two, I’d need a dyno to tell you which one was better.
Thanks for the reply, my LD has the TQ mods plus when I got hold of it the WHOLE divider had been removed along with just about everything else in the plenum, it's not a pretty sight, I'm thinking the mods haven't helped it. Its in a 68 Dart has around 10.8 or 9 comp Eddies at mid 280's hyd / roller 222@.050" 1.6 rockers 999trans and 3.5 gear, It's gone 11.50 in really good air, it could probably use some more cam but I'm old and grumpy and more cam will drive me crazy. I'm thinking if there might be a bit in the AIRGAP for me I might grab one.
