can i get a super charger to fit/work with my lg4 305 and quadrajet 4bl?

 

Yes, blowthru quadrajets are very easy, you need to drill and lock the secondary flapper with a set screw on the bottom if your going to run a carb hat. The choke is not effected either way, so do not mill it off. Just tune your fueling properly with the right rods, boost referenced fuel pump, etc. I believe Vortech sells a universal system that is cheaper than the Prochargers that you can adapt to your setup, you will just need to fabricate the charge pipes and do your own Intercooler...
