Of course, it also carried the seeds of the eventual fall.
See, the base setup in this car was a 256bhp 389 V-8 with a 2bbl carburetor and a 3-speed manual transmission. Or you could get the same 2bbl 389 with a higher, premium fuel only, 10.5:1 compression ratio and the 3-speed Turbo-Hydramatic gearbox, rated at 290bhp. There was also a no-cost 265bhp low-compression 389 available with the automatic, if you wanted to burn cheaper gas.
Optional engines included a 4bbl version of the 389, as well as a Tri-Power 389 (three 2bbl carburetors), a 4bbl 421 V-8, a regular Tri-Power 421, and a 421 H.O. also with triple deuces. The performance "2+2" package added further options like a Muncie 4-speed manual.
That's something like three transmissions, seven or eight engines, no fewer than five different final drive ratios, et cetera, ad nauseum.
That's a lotta SKUs, as it were.
You could really tailor your car to your tastes that way, but when the Japanese hit the market with "You have a choice of maybe two engines, two transmissions, three option packages, and pick your color," it really simplified things.
