Two tone...should I ?

Yes all in one person's tastes.

Mopar guys have a history of being all about ALL MOPAR, and black engine compartment screams GM. Sorta like using GM terms in conversation with Mopar guy, like "posi"...etc....screams GM.

NO doubt the majority of our A Bodies are not considered rare or really collectable per say..... most ( no not all), people that have a original 340 car tend to restore it back to original. With maybe the exception trying to add some HP to the internals of the engine.

A guy with a slant dart will usually change it over to V8 power, and maybe make changes to the car to suit his tastes..ie paint, interior, gauges, scoops, etc

We all have different view points and tastes and so be the hobby. All is good.
