The injector angle isn't that big of a deal. Many OEM manifolds, including
the 5.0L "chef's hat" just shoot at the port floor. The reversion pulse
takes care of the rest. Hitting the back of the valve is for cold start and
idle emissions so most of the newer manifolds aim there.

Ipsco makes nice screw injector bungs. You bore and tap the runner.

Those weren't from me. I didn't supply all the info on that panteraplace
page. The only EFI Clevelands that I have dyno data for are converted carb
intakes.

No I don't. I'd prefer a larger plenum so the walls were away from
the runner entry. The converted tunnel rams work pretty well in a
Pantera with the throttle body opening at the rear.
