For that build, I would consider any of these suitable;

-RPM
-Holley SD
-m1 single plane
-original Torker
-TM6

And fwiw, if this is strictly a "race car", I'd put a bigger cam than that in it if it were me........ And then more gear along with it.

It would have been interesting to see how that old Weiand intake would have done in that old magazine shoot-out.
