I looked at those, but I liked the fact that the Holley's are still made in the USA and I believe the cost of the ProForm vs Holley (aluminum) is not that far off anyway.
I still need to tune a few more things. I think I'm on the right track. But so far, you can see an improvement in idle quality and the A/F gauge shows it too compared to my first video. This is also without replacing the main body. So, it cost me less money so far.
