Very interesting, Jack. Does it look like it would be possible to continue milling to clear out the area between the primary and secondary openings and between the two primary openings as well? If so, we could eliminate the spacer plate now required for all the modern four butterfly EFI throttle bodies. That plate is only required to keep the butterflys from hitting the solid top on the stock manifold. If that whole area can be milled out then the air flow through the throttle body and into the manifold would also be vastly improved. As it is now, with the spacer plate the air has to pass through the butterflys and then turn sharply across the solid parts of the top of the intake manifold. Without that spacer plate most of the modern EFI throttle bodies are about the same height as the stock Qjet so the air cleaner would clear the bottom of the engine cover without any further modifications.

got a stock manifold and cleaned it up:

had it hotdipped and magnafluxed: Standard crack from what I can tell:
http://www.gmcmhphotos.com/photos/atomic-tbi-fuel-injection/p64839-magnaflux.html

Milled down to crack in floor of intake:

drilled and pinned crack ends:

Finished crack repair on floor of intake:
http://www.gmcmhphotos.com/photos/atomic-tbi-fuel-injection/p64842-finished-smooth-floor.html

Intake throat finished:

Repaired Intake ready to install. Will use block off plates on the exhaust crossover:

Have another aluminum filled intake coming, for I would be more comfortable with the intake filled AND block off plates, but now have something to
keep it running with. I'm really looking forward to milling down the Edlebrock Torker and hoping I can get the MSD Atomic and stock air cleaner under
the stock engine cover.

Thanks Everyone!

Jack
