570 Holley Street Avenger w/ electric choke and ford kickdown (includes secondary vacuum springs, and holley dual feed line)- For Sale I bought it new 3 years ago for my '57 312. I have the box and owners manual. I've decided to move to something else and was going to keep it as a back up, but I need $ for a mummert cam 
I'd like to get $200, they are $325-$360 new - Make me an offer. Thanks! - John
