Wow you got a Quadrajet to work in a blow-thru application? What mods did you have to make to the carb?

Also, is it intercooled (looks like it) and did you do the piping yourself?

That's a unique looking setup, and I like that it's kinda budget thrown together, totally my style!

And is that the only mod you did to the quadrajet to make it work in blow thru? I was under the impression that boost referencing a quadrajet was a no-no.
