There is no reason you couldn't. IIRC there was an article on some guys who put EFI on a either a Hemi or Big Block mopar and did the power tour a few years ago. They used two OEM throttle bodies off of something.

They used the C/R with the removable tops and had the wiring harness hidden inside the plenum, very sanitary installation. Interesting, that is the manifold I plan on using, I will check it out!
The funny thing about science is that if you change one miniscule parameter you change the entire outcome to the way you want it.

Use dual throttle bodies and then you don't need to worry about the plumbing and wiring. FAST makes a good dual throttle body system or you could use dual Holley Terminators. Call Rich at FAST Man EFI and he'll tell you what the best way to put EFI on a cross ram is. I emailed him and he got right back to me, I will call him next week. Thanks again!

How satisfied were you with the final injector orientation in that set-up?
It certainly looks cool, well executed, and meets all the objectives for stealth, but I'm wondering performance, flow disruption, etc wise, what it leaves on the table.
Reality check, that half the population is smarter then 50% of the people and it's a constantly contested fact.

I did dyno this engine and it did well, but I have no before and after numbers. Obviously, this was a street/show car so all that was needed was good driveability and it had that in spades. That is the ultimate goal driveability! The customer dosen't care that much about utlimate speed and quarter mile ability, he just wants to turn the key and have fun, which in the current state of tune gets old very fast!

Troy’s Hemi Dart cross ram fires right up. Even dead cold (So Cal)
Maybe has to do with a large plenum and crevices for fuel to puddle??
I know he put a LOT of effort into tuning it and cam selection upfront. Of course he built it, maintains it, and drives it. Having a knowledge and responsibility from cradle to grave goes a long way.

A cross ram is the wrong intake to choose if the customer wants the engine to fire up easily and drive nicely. If the customer is willing to spend a bunch of money for an EFI conversion then it could be made to work. Not sure what the bill for a conversion like that is going to be, probably several thousand dollars. Money is never an object with him, he had the car built as a Hemi Dart clone and likes the look, just wants better driveablility as he is tired of cars that aren't fun to drvie.
