ALUMINUM 430 CanAm motor
Before the 1969 ZL-1 motor arrived GM supplied some of the CanAm teams like Mclaren with special engines. It was a big block style motor with aluminum block and heads. It was set up to run a 'dry sump' oiling system. A characteristic of the motor was a bigger bore and shorter stroke than a normal 427. Does anybody know what the bore and stroke measurements were? It was a 430 c.i. motor with the standard '430' type (NOT 427 type) crankshaft. There were less than 100 blocks cast.
In 1970 some of these motors were modified and displaced 495 c.i. Cylinder sleeves used in the aluminum blocks created some challenges. A normal 427 used a 3.76" stroke crankshaft...
thanks
