ok so I'm trying to figure out what I got my hands on I was cleaning the motor and surprise I got a blue block so I looked at the number on the front number and got k06798000 and went and looked it up and huh my 74 has block from 79 thats cool and all but that means it being stock is in question you know wrong parts eventually. and yeah I'm gonna do a visual check I got to drop the pan to get the timing cover back on anyways so ill check if it is indeed a 4 bolt or 2 bolt Im thinking it is but not 100% any ways next I pulled the head numbers which are 462824 or 482824 | 60-3 | gm 14 front to back and the intake number 340261 gm-3 any know what I got on my hands? thanks much love!
