When the project started, the engine choice was an open question.
For 1973 the 225 six was dropped, with the 318 and 340 V-8's being the only engine choices.
During the 1975-76 model years, the top engine choice was a 350 cu.
A 2-door convertible model was added in early 2011 with the same engine choices.
Engine choices in the pace cars were the same as the regular Z28.
Engine choices remained the same, except for higher power ratings.
The engine choice appeared to be a failure, though.
There are 8 models of the Coupe based around two engine choices.
Engine choice was similar to '62, with the small-block and V8s the most popular choices.
From 1915 to 1924, only sixes were offered, except for 1916, when a V8 made a one year appearance as an engine choice.
