need help with my 454
 

Attachment 12556



this is the code i found. in case it does not load i found a stampin gm 7.4 l g on the passenger side. what does this stamp mean? can it identify year of assembly of motor or not? if not were would the code be to identify it ? i do not belive the motor is stock as it has an l meaning 350 in the vin code

It means it's a 7.4 liter, or 454 cid.

found a number behind the alternator and near the flywheel cover
 

this is the number i found ce3304607. i know its a 454 or 7.4 liter does anyone know what these numbers are and what year the motor is and what app it was in befor it was put in my k10? im sure its not the orginal motor
