but that had a plenum.  CanAm cars that used Lucas metering did the same.

I think you might be right but I'm still wondering if anyone has done this. . .

I think it would be fine for a race car.

That what I thought at first but it doesn't do that with tbi (maybe because tbi
works with less pressure?). I don't know that it will actually hit. It might
depend on how far above the blades the injector tip is.  And it sprays so little
at idle that I think the atomized fuel might just find it's way around the
blades (vaccuum) and work ok.  Sure the spraying fuel is under a lot of pressure
but it's also atomized and there is a fair amount of vaccuum at idle. Maybe the
tip of the injector will have to be some minimum distance above the blades to
allow for a smooth flow around them.

Talked to a couple of pros about this. Depends where you want them welded and
how thick the metal is there.

It will cost you, but worth it.

I have. And talked to them on the phone. They do it a few different ways: One,
with Lucas metering (not EFI but makes no diff in this case),  bungs welded into
the ram tubes and sprays fuel down onto the throttle blades. Another (most
common for Kinsler) is below the blades BUT spraying from the outside at the
opposite side of the intake runner wall instead of toward the valve. According
to the theory above, the fuel would then splash off the opposite wall and drip
into the cylinder. But I'm not sure it really does.  Yet another (actually own
one of these) is a 3 piece magnesium intake from a chevy SB (well actually
"Pontiac" but in name only) turbo gtp car. The throttle blades are way high
(maybe 10 inches high) in the runners with the injectors just below them on the
inside of each runner- so there is still probably a good 9 inches of wet flow
before the fuel makes it into the head...(quite a contrast with the direct port
injection used on some sprint cars) I called kinsler a few weeks ago and asked
if this adapter method would work and they said they had done it using a Hilborn
setup on a hemi and it worked great. But admittedly that was a race car.

I guess there's no way to know without actually trying it. . .

thanks for your input it IS appreciated!!

2 things here- the original post said adapters were going to be used in order to
avoid welding. ie...so it wouldn't have to be "butchered" as you put it. 2nd-
there are a lot of modern efi manifolds that are virtually nothing more than
these "antiques" with cast-in provisions for efi.

So I gather from your responses that you haven't done this?

cheers
