They are small block chevy headers../QUOTE]
Actually, you can saw off the head flange on sb Chibby headers and weld them right onto a SB Chrysler head flange!!
Why? he asks. Why of course. SB Mopar in a Landcruiser, that's why
They would hit everything in an A Body for sure by just replacing the flange.
For the price and the fear of smacking the ground, it looks like the Shorty Header did fairly well in the comparison! In a street car you will NEVER notice the difference of 8HP & 12lbs of Torque, no way NO HOW!
