Edelbrock LD340 WTH?!?!?

Hype in the same way the 280/280 purple shaft or XE268 cams are done. Someone built one that worked well 25+ years ago so that's the only thing that people follow.

My opinion the Weiland manifold looks the closest to the LD340.

I did EFI and switched from an air gap which worked well to a Super Victor EFI and honestly I think it has better low end than it did before even with a "3000-7500 rpm" manifold. Can literally pull a hill at 1400 rpm in 6th very easily with that manifold and a 227/231 duration at 0.050 .530 lift on a 110 hydraulic roller. With a carb its different but if you don't want an exhaust crossover, just buy an air gap.
