[DeTomaso] IR EFI experience - Not sure if original post made it so resending

[Kirby Schrader]

I’d have to go back and look… Yes, they are IDA.

In my case, for the GT40, I needed a new cast manifold. It’s on a 9.5” block….

Maybe that's where the Aussie Speed 351C IDF manifold comes in handy, low profile and can be made to work with IDF's with a filter atop and still fit under the stock decklid and engine screen, so if the TWM TB's are no taller than IDF 's and of the same bolt pattern then Kelly doesn't need to cast any manifolds.

I would love to hear from those that are running one of these systems.  One of the systems I am considering is Kelly Coffields system so I am particularly interested in any experience with his product.  I know Mad Dog is not on this list so if anyone has his email I would love to get his opinion as well.  I am working with Dan Jones on the motor design right now.
