Looks very original - looks like the factory pin striping. https://longisland.craigslist.org/cto/d/1977-pontiac-bonneville/6516051887.html
Has the little 301....... Also has the 'regular' A/C control unit (preferred), rather than the 'automatic' unit that i have....
That heater hose is awfully close to the compressor pulley\belt... which is odd considering the routing bracket is still there to route it correctly. And yeah... 301. Not awful but not going to set the world afire. The 1977 model 301s had some design issues that weren't corrected until the next model year...
And the funning looking early "Duel Jet" Carb, that still used the larger Q-jet body with no secondaries. I always shook my head on that one. Compared to the later years that actually only included the primary side of the casting.
Yeah, that was sooo weird...IIRC, the intake also doesn't have a chamber under the 'secondary' part of the carb.
