I have a set of Holley 450's (part #9776) for sale. Very clean and run great. They were just gone through by C and J Engineering in Sante Fe Springs, Ca and have been modified with 50cc accelerator pumps on both. They run great together. Haven't had any problems with them. Selling because I want to try something new. I have them set up on a tunnel ram on my bbc in a vdrive. SELLING AS A SET FOR $650. Will include fittings and brand new regulator.
