This is a one year only, specific for A-body GS 455 and Stage 1 only. Brand new in the GM box. Pics upon request. Asking $500 plus shipping. Payment by postal money order only.
Just the angle on the return line nipple on the backside compared to a 350 w/o A.I.R. The 350's that don't have A.I.R. use the same pump/brackets as a '71. I know from experience that a 71/2 350 reservoir will not work on the 72 455 because of this.
I wouldn’t mind pictures 1960josephine401@gmail.com but a lot of money for me probably unless you need some parts I have to barter on : )
