Curtis,
Thats one sweet set of headers you built. Your car looks sweet as well. I wish my racecar looked as nice as yours. Your E type is also very sweet (someday I will have one)
My roadster is my first car, and I have built it from the ground up. Here is a poorly updated site for it.
http://www.cardomain.com/ride/737676/1 I'll be honest, I do find it to be more fun the the Alfa, but its a different creature all together. The Alfa is good for looking good while going where ever I'm going, the roadster grabs attention due to its ungodly loud exhaust, and its unassuming speed till it runs out of gear (provided I can actually put the power down out of a corner and not drift out.)
I will see if I can find more info on your car from the Datsun side of things. The website that hosts the pics I posted might have more someplace.
Will
