Normally when you see a 3 letter suffix, that usually started in 1970.2 letter suffix prior. TCK is a 1970 truck 155 HP 250 Six.

Hah! So obviously not the original power plant. Makes sense 'cause when I went to get a new fuel pump it became an ordeal. Thank you so much for the info... now if I can figure out why it's smoking... compression within 10lbs across all cylinders and doesn't smoke when you first start it so I am hoping it's just valve stem seals... runs so quiet.

Thank you again and Thank you to your "Apache Pilot" for their service. I have one son in Afghanistan for the 3rd tour and one that is a vet. God bless our kids...
