I have been on all the chevy sites and trying to identify my motor with the numbers on the block and im going crazy. I was told it is a 305 but i just want to make sure so i can get the proper specs on it.
back of the motor drivers side 5.7 Lt LGI
back left driver side OF165
back passenger side 10243880
underneath left freeze plug H39
underneath right freeze plug 378
does anyone have any ideas?????????
