Original poster. Street car right? Why not just run a stock 71-78 cast iron intake? Heck probably get one for free if you bug enough buddies for what they got laying around. Worst case scenario maybe twenty bucks.

Thats a 79 but I wish it was a 78 because of that stupid tin thermostat housing they started using and turned 45 degrees starting in 79. I missed that completely until after I sand blasted and painted it.
