http://cgi.ebay.com/ebaymotors/CHEVR...Q5fAccessories check this kit out. a big block would easily provide the airspace for this set up. it allready has a boost referenced fuel pressure regulator. the only things that you would have to buy is or build is the exhaust manifolds. do big block shorty headers and flip them upside down you may have to cut the collector and re tig it to tuck the snails under the hood a little better. this kit is a really good deal though. you can get this kit a little cheaper then that as well. ive seen them go for as cheap as a 1g flat with free shipping. and you might even be able to talk to the guy and tell him you dont want the exhaust manifolds. for cheaper prices ya know. anyways i hope this helps. oh and DEMON makes a production blow through carb allready and its cheaper then sending in a carb to have the base plate vaccum ports added and teflon floats and boost referencing the meteoring blocks to constantly equalize the pressure. you will also need a higher pressure fuel pump. more then your average 6-8 psi fuel pump.
