Tim the 1969 Corvette is a better choice. 1968 Corvette models suffered all the usual problems of a new model, when introduced by GM. Zora was in the hospital when the final development was done on the new 1968 Corvette. He had serious concerns about the 427 models overheating. This issue was not addressed in his absence. At the last minute in 1967 before the Press Preview he ordered some changes and as a result, reduced the overheating problem. The new styling was interesting but it proved to be a nightmare for the engineers.
Terry had a restored 1968 Corvette L88 that sat for ages before he was finally able to move it.
As you know Chevrolet had two versions of the L88 in 1969. They got the improved "open chamber" aluminum heads part way through the year; saving the best for last. The early 1968 models are especially bad. C&D refused to test the one they were given; it was falling apart.
