Starter height

I want to buy a set of headers but I keep seeing they are for a high or low mount starter :scratch:. What is the difference-I have asked the sellers but they dont really give a very good answer. Should have come here first I know :thumbup:

High starter: Starter mounted above the oil pan flange. Just about all cars. Might be some "fleet" cars with the v-8 727 trans with the low starter.

Low Starter: Starter mounted below the oil pan flange. Some trucks with the heavy duty 4 speed trans, or early V-8 727 auto with the adapter plate.

What year body style vehicle are you working with? Very little choice on headers in 66 down "A" bodies. Nothing for the 170 engine, without modifying the header.
