Re: Lt1 -93 or 94-97 intake manifold
Lt1 -93 intake casting nb 10208145 has no crossover pipe between fuilrails behind map so it has straight inner roof.
Rectangular ports with injectors located straight pointing to head intakerunner
Lt1 -94-97 intake has a crossover pipe between fuilrails behind map and create a small bumb on the inner roof just after Tb.
Ports match more or less to the head and sized as the head intake runners+injectors are angeld against intake valve.
You can see a few -93 intake on 93-98 f-body so i just wonder if missed something.
