Mark III - The Full Story

(so far)

Pictures of the Mark III Project

Overview

Well, the best way to judge the progress of the third mark of Z, is to compare previous drag strips outings. I never really considered myself a hard core drag racer, but the more curious I got about the performance potential, the stronger the addiction got. Besides, it's a lot easier on my driving record to do this legally. Especially as the car got faster.

8.9:1 compression
Performer RPM intake
Holley 650 cfm 4160 double pumper
