Pontiac's 428 was a sneak attack in the muscle car horsepower wars

It’s the end of April, or, as we like to call it at Hagerty, Engine Week. We’re celebrating some of our favorite big-inch V-8s from the peak of the muscle car era. Today is 4/28, so it’s time to pay homage to Pontiac’s 428.

Regarding Pontiac external engine size: I remember when I (as an old Chevy guy) dropped the 455 into my '66 LeMans.  I was talking to a Poncho guy, and I said something to the effect that "I didn't have any experience with a Pontiac big-block".  He set me straight in about 6 seconds.  Now to a Chevy guy, it seemed inconceivable that an engine with 455 cubes (and replacing a cracked block 326) wasn't a "big-block" vs. a small-block.  My first lesson in Pontiac powerplants was a little embarrassing, but I'm glad the guy was cool about it instead of laughing me out of my own garage... 😃
