Well, I have not pulled the old power valve, but using the Holley way of checking...I used a vacuum gauge with the car warmed up and in gear. I pulled only an eight on the gauge. Holley stated to cut that in half, so I bought the 3.5 power valve. I have not put it in yet, but I am thinking I have the stock 6.5 power valve.

I hope to change it out tom before work and update, I will also check the throttle linkage as you stated.

thanks,
Ryan
