L88 - 427ci / aluminum heads / cast iron block / 430hp / Corvette option, there were early and late versions, massively underated

LS6- 454ci / 450hp ( 460hp in the Vette ) Chevelle usually, but Yenko, Nickey, Baldwin-Motion would stick it in any chassis you wanted short of a Corvair.

LS7 - 454ci / want to say 460-465hp but I may have to look it up, not officially offered in a car from the factory but no doubt "found their way" into some and was a dealer aftermarket engine package.

221ci or 260ci for the Ford small block

Ford and Chevy made 427ci big block

Sunbeam Alpine Tiger

Toploader means that the gear assembly loads from the top of the transmission case

440 Magnum - Hi Po 440ci big block with 4 barrel, 268 degree cam, high perf heads, high flow exhaust manifolds; same basic package was used in pursuit package for police work ( '69s were legendary, those bricks would sail to 150 mph )
