1969 428SJC
I have a 1969 special order Torino Daytona Cobra that came with the 428 SJC motor which has all NASCAR running gear. The motor was bored .060 over by the dealer. It came from the factory with 427 lower end including NASCar rods, 427 heads and other goodies. It has an Isky 312 duration solid lifter cam with .630 lift and 93 degrees of duration. It came with an aluminium high rise intake with an 850 Holly double pumper hogged out to around 900 cfm. All I have changed was to replace the original Mallory ignition with a Jaclbs as I like them and the Mallory kept going bad. The motor is a little radical for crusing around town and starts to smoth out at around 3,400 RPM. I got the car brand new in February 1969 and have had it ever since and it has been great.
