Lt1 -93 or 94-97 intake manifold

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.
