Was the 70 setup the aluminum Edelbrock intake, I thought that was the later 71?
My 71 had an iron 6 pack intake (non original of course). what a monster to try and remove in the car. I thought the iron ones were the 70 model? Maybe they were just for the 69 roadrunners? Either way I traded it years ago for an aluminum one as I was tired of lifting it on and off to reseal an intake, change cams, etc. Probably a bad idea in hindsight 15 years later. very impressive and awe inspiring, but a four barrel was easier and cheaper to tune. Good luck with the sale.
