Holy cow… I know of one that went for less then $400 a couple of months ago

But no matter what I tried, the intake would work well in one part of the rev range, but not across the board. The one thing I never tried was throttle body injection.

I’ve done a ton of screwing around with the early 80’s crossfire setup (basically same design with smaller runners) and always loved it… much better power production across the power band then most comparable setups once you figure out how to work around it’s limitations. I like it so much that I’m converting my full size truck to use one.

But ultimately, I think as a wet flow design, that intake manifold just does not work on the street. And it's not really feasible to mount direct port injector nozzles unless you could somehow come up from the bottom.

Donno, if you think outside the box and turn it into a semi wet flow setup you could get around it’s limitations and have some interesting advantages. I’d move the injectors to the lid right at the runner openings, that way you can use the cooling/detonation control/mixture advantages of wet flow with the delivery and control advantages of dry flow and fix any possible puddling issues that you get with with TBI/carbs
