1975 260 or 350 v8 ?
 

How does one tell what engine is in the car..
Past the air cleaner decal and emissions decal..


Sorry if it is a stupid question.. I'm new to Olds ownership.. Well, Family has had them when I was younger, and I had one as a teen but it was a 50.00 car and well.. That one, all that mattered was it ran.. This one is more of a keeper..
Thanks
