https://forums.edelbrock.com There's a section for the PF 4 there. Lots of info. I have one on my truck and there are a couple of others that have them here as well. I don't have a square body, so I won't get into my setup, but the other two I was referring to are sq. body owners and hopefully they will chime in. I will say there have been a few issues with Edelbrock's sump. I'd look at other avenues for your fuel supply.
