Re: Before you buy your next carb, READ THIS!
Awesome info Eric. I have the original Holley off of my 1970 Z-28 LT-1 350 which has the stock mechanical cam. It is a 780 CFM vacuum secondary unit as you described earlier and was rebuilt by the previous owner who replaced the power valves. I was wondering what the correct power valves would be for the carb? I had heard 8.5" opening calibration was correct.
Thanks, Paul
