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.

Actually there are three different LT1 intakes.

The 1992-93 intake (10208145) has no fuel crossover and rectangular ports. If you run this I would modify some of the later fuel rails.

The 1994-1996 (10106830) intake has a fuel crossover and rectangular ports.

The 1997 (12552138) has a fuel crossover and ports that almost match the head.

Some comparison photos. The red intake is an LT4.

The 12552138 intake is the way to go if you locking on port shape and the injector angeld against intake valve.

I have the 630 intake on my camaro so i might change.

You can find the 138 intake on the -96 f-bodys as well.

I feel it is worth changing........
