All that iron and only one shevy? Fer shame!!! But I do admit, those Rancheros are pretty cool. I have a motor from that same year Monte,76, in an 85 shevy van. I bought it that way, someone else ruined the Monte. I'm assuming that it's the 3970010- 350. And one of the major mags' editors have really bragged up the 882 heads on that motor. Sounds like you have a pretty cool collection.
