#ChevySmallBlock

On paper, a super-lightweight Lotus with a genuine ’68 Corvette 350 and Muncie 4-speed ought to eat up a road course; just go onto any online forum full of self-proclaimed car experts and they’ll tell you exactly that. Reality, on the other hand… well, reality doesn’t always live up to the expectations of internet car experts.

After painstakingly building a medium-hot 406-cubic-inch small-block engine to replace the Impala’s very tired 350 (motivated by the car’s lackluster quarter-mile performance), 1998 became 1999. Finally the New Engine was ready for swapping.

Before packing up the Impala and leaving Georgia in the fall of 1996, I took the car to Atlanta Dragway and ran some semi-disappointing low-17-second quarter-mile passes. Back in California, I resolved to make some improvements to the car’s running gear. After 15 years as a cheapskate, junkyard-centric gearhead, I was finally willing to spend substantial cash for new aftermarket performance parts. The main question was: what kind of engine would I build?

I wasn’t going to do this car today. But venting my spleen on yesterday’s 1971 Ford Galaxie 500 and all the discussion it prompted forces the issue: what was the best of the big popular-priced big cars of the era? Having handily eliminated the Ford from the running leaves a tough choice: The Plymouth Fury/Dodge Polara, or the Chevy Impala. Now I have a pretty major soft spot for the big Mopars of the era, and I wrote quite the paean to a ’69 Fury here. But that memorable ride was colored by the circumstances of the day. Truth be told, both the big GM and Mopars had it all over the Fords, but there were a few crucial differences between the two; one in particular.
