72 340 warranty block

If you have a build date of 1/72 then the casting date on your motor should be somewhere in the 4th quarter of 71......Keep it consistent with the factory logistics of supply line available to keep the production line running. I have a 71 or 72 340 in a 69 Barracuda I am going to swap out in the near future for a shiny 360 stroker that is sitting on an engine stand eager to be commissioned. The motor runs and the car has been driven by our family for the past 5 years. I will send you the casting information tomorrow.
