Got the Dynatech headers installed, got them from Pro-Touring F body. He's a great guy, even cut us a deal on shipping to help on the cost of long tube ceramic coated headers. I think they are 1 7/8 primaries into 3" collectors. Got the engine harness layed out and plugged in, working on where to mount the computer, think we are going to go through the firewall and mount it above the Vintage air box.
