Can Am BBC

[markus37]

Calls for a definition of terms...Jim Hall was an early tester of the ZL 1 engine for GM in his CanAm car and Lemans type car.Those were originally liner blocks as I recall. What were generally referred to as CanAm blocks were developed by Reynolds in partnership with McLaren Racing using the high silicon aluminum as used in the Vega. I had one of those in my garage several years ago..modified for a roller cam.Chevy continued to sell the lineredZL1, then in 1974 gave,Don Yenko the right to produce and sell them as GM wanted to discontinue them.
