Assembling the COPO motor required a long search for authentic 1969 427 corvette parts. Frank found the "512" casting number block on-line in Chicago. The heads are "291" 435 HP vette heads from Ohio. The "163" winters intake is from Iowa.

After collecting all of the external parts, including an authentic bolt kit, 780 CFM Holley and 69 date code water pump; the assembly task was left to JMS racing Engines in Monrovia California. There, Mike and his crew machined and assembled what looks like a factory built 1969 427, but it will run on todays pump gas. Even at 10:1 compression it makes 473 horsepower 493 Ft. Lbs. of torque! A bit more than the factory motors turned out when put in the Camaro.

James and Troy consult the manual to make sure they are routing the breather hose according to factory specs.
