Guys,

trying to determine when vin stamps started on 1967 pontiac engines. Motor in question was in a car built the 2nd week of June 67. Everything I find says the vin stamp started in late 1967. Is there a timeframe that is documented as far as when this started. Was it in late 67 for the 68 model year? This motor has no vin stamp.

thanks
