I'm selling my holley 750 its a 4150 series double pumper. I have it on my Camaro in my garage. I haven't taken any photos yet but if you dm me I can send some. It's still brand new and never had a drop of gas run through it. I had it built by Kevin at CSU back in 2011 but I haven't been able to get my turbo project going. I'm asking $850, they're 925 plus shipping from CSU. I'll consider a trade for another holley and some cash, a 650 double pumper or a 670 street avenger etc., something more suited to a naturally aspirated 350.

 

This blow through would work for you centrifugal super charger guys as well as turbos
