Take a look at this:
It was made for a GT6, but the principles are the same for the 1500.

If you were doing an A Series motor I would suggest you get a single SU
intake and run a single throttle body type injector. The Siamese ports
the A make things funky for injection. But, since you mentioned Strommy,
assume you are doing a Spitfidget. There is no reason you can't make an
intake manifold from steel or stainless steel. Use a gasket as a
cut a 1/4" or 3/16" plate and ............ You get the point.
If you come up with a nice port injection system it would be easy to
blower into the system and have some real fun.
