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.

How many of these setup's have you seen? I couldn't find any where they didn't cut the car apart with twin turbos....motor trend did a piece on this setup and more than enough power @ over 500hp 10psi
