Wiring Stock Tach September 22, 2008, 07:29:34 AM I am completing a turbo coupe to a "408" and wonder how you folks resolved the wiring of the stock tach to read correctly with an 8 cylinder engine? I am running a MSD digital ignition. Quote Selected

Wiring Stock Tach Reply #2 – September 22, 2008, 02:34:47 PM It's slow going as I only get 1 day per week to work on it. The motor and transmission are installed with a complete magnaflow exhaust. I am having some driveability problems(surging at idle) but I am checking the calibration on the mass air meter. I was hping to use the stock hood and I bought a Roush hood scoop, but the TPS is still too high. I will send pictures when it is completed. Quote Selected
