LT1 in 3rd Gen header question
So do 4th gen headers for the LT1 work in a 3rd gen? Or do you need 3rd gen small block headers? I am also getting two answer on what size the tubes need to be. Please let me know

3rd gen sbc headers.
as far as tube size, what have you done to the motor? Is it stock?

have you looked in the LT1 swap section inside the Engine Swap forum?

They also sell the D-port shorty headers made by Hedman, which fit a 3rd gen and bolt up to the LT1. There are around $250. They also have a y-pipe for these headers.
