Cam and torque converter should be the last 2 things you buy for a project motor. First, verify what motor you have. There is a suffix number/letters stamped into the block at the very front of the passenger side, very close to the top water pump bolt on the passenger side of the motor. That will tell the application of the motor as it left the factory. The other identification is at the rear of the block, on the driver's side, just forward of the bellhousing flange. This 7 or 8 digit number is raised and cast into the block, rather than stamped like the suffix numbers. If you will give us these numbers/letters, we will find the codes for you and determine that you have a real 350, rather than a 265, 267, or other motor that you don't want.

The other thing is to remove the valve covers and read the casting numbers of the heads in between the valves.
