This is a Roush 511 8 stack EFI.

Great info, everyone! And thanks for the pron, which does nothing except reinforce my direction. It's an expensive direction to go, I know, but I plan on building only one of these so why the hell not.

I'll look at all the options (including the Weber carb route) and get all learned up before making any decision. Heck, I haven't even started the build yet, so I'm a good ways out on getting the engine.

Thanks again.

Guy's Have a look at the engine photo of my 427 s/o, it has a set (4) x 48IDA webers, however after being in storage for 14 years the webers were not in great shape, so I decided to turn these into injection fed, it was an original Inglese system purchased in 1993.

It took about a week of work, removed the chokes, and away we went, out with the old in with the new, today very few people can pick this is a fuel injected set up. The webers with Race setup (42 chokes, etc) 335kw at the wheels, with a street set up (37 chokes, etc) 315KW at the wheels, injection setup 370kw at the wheels (1 KW = 1.346HP) that equals approx 640hp at the flywheel. Go injection, the best part, everthing is hidden, looks just like a weber setup. Love webers, but injection just makes sense. Better idle, better fuel economy, A/c cut out on full throttle, engine idle step up for A/C, ignition timing tuneability, multipule engine setups, etc, bla bla bla.

I would never of done this with a new weber setup, but for a system that was in need of major refurb, it made sense.

I have the Roush 427IR 8-stack EFI too. After the altitude issues were fixed it rocks. I get 17-19 on longer drives, but only 12 or so just driving around town.

I would avoid the Accel DFI setup. It's not that it can't be made to work, but as described elsewhere that thing has so many knobs it's just hard to get it tuned right. Even Roush changed to a simpler system in the newer revsisions.

Unfortunately with Roush you have to buy the whole engine to get the stacks (although it doesn't hurt to ask). I like the looks of the Dynaformance setup.
