New member-motor question
Greetings - new member here...
I just bought my first C3, a 1975 coupe. (today)
I'm just now trying to hunt down the engine number. I've looked everywhere, no luck yet.
The PO did state that he thought the motor was not original.... and I really don't care, except I would like to know what motor we have.
The only CLEAR stamping I can find is GM 42 on the left rear of the motor.
There is another number just a bit lower, but it is so hard to make out. Hey, I'm 66 and the eyes are about shot.
Anyway, any insights as to what I have or where else I can look, would be appreciated.
No numbers can be found on right side at all.
Pics of the car and best shot I can get of the motor....
I'm sure I'll be asking a ton of questions along the way.
This is my 2nd corvette, had a 69 way back when I was like in my early 30's.... it was a basket case.
The 75 has very good bones... body mounts are great, car runs good, most curious about that motor though.
Thanks,
Len

Engine suffix is located on passanger side block pad just in front of the head.
It is a stamped number onto the block, which should also contain your partial VIN serial #.
If no number is present it has been machined off for a rebuild of the engine.
