Good Day Folks,
I have a 454 in my 72 c10 that was in it when I bought it. I want to tune it but find out I need to know the engine mfg date as tuning specs have changed over the years. I have found the mfg date on the front of the engine passenger side it is T0106TRK and the casting number is 3999289. I for the life of me can’t find the date code which will allow me to decipher the mfg date. Can someone tell me where the heck this number is, or the date the engine was manufacturd? I looked everywhere I can with an inspection mirror and come up empty.
Any help will be greatly appreciated.
Thanks,
Bill
