Those are sweet. If I didn't have other options, I'd get a couple.
I decided to go w/the Harms' kits b/c I have a guy locally here that does Shaker conversions that you are unable to detect (yes, I've had a real Chally hood to compare and he has a real cuda Shaker to compare) from conversion.
Plus, I really would like a non-crumple zone 1970-style for the Challenger.
Now...if someone would repro a four-barrel base plate that will work w/standard 5 1/8" carb throats for Demons/Holleys and work w/hi-rise intakes.
Shakers will be quite popular now, but there is a need for working w/non-stock inductions.
Tim at FHO already makes a dual-quad baseplate for the Stage V intakes.
I need to figure out something for the FBO six-pack EFI setup for the Gran Coupe.
