408 tuning with a Wideband sensor

I decided to go with the Proform main body. The mod to the one that I have would be simple but I like the fact that the Proform gets rid of the choke horn. I never use the choke anyways. If anyone is looking for a manual choke main body for a Holley DP I'll let it go pretty cheap.

Where did you get the Proform at and What was the $$$ ??
