Thats pretty cool. I saw a guy that used one of those EFI lower intakes to create a 3 x 2 bbl set up.
Ingenuity at it's finest,I am constantly amazed at just how talented guys just taking the time to think outside the normal ways of adapting common parts and transforming them into what is needed, HRP
Here's something similar I found on here awhile back on an older post. Pretty cool. I wish I could find the thread again. 3x2 on an EFI lower truck intake.
Three of these would look cool too,Weber style design and a good price: http://www.allcarbs.com/detail.php?pid=1475&mfgn=40&ctgn=10&stt=45&gb=2 Also would work on a 223 6 cyl multi-carb intake,the adapters are inexpensive too.http://www.allcarbs.com/detail.php?pid=599&gb=1&ctgn=1&stt=5
