West Central Iowa
Have been reading on here about converting the 427 Chevy in my C70 truck from the Holley carb to Edelbrock. Seems I have 2 choices with a manual choke. The 1405 is a 600CFM and the 1407 is 750CFM as I understand it. Which would be the best fit and what did you use in your conversion? All comments appreciated.
