The EARLY 1949 Cadillac 331's came with 2 bolt valve covers and then later went to 4 perimeter bolts. Anyone have an early valve cover they could measure the center to center spacing of the 2 bolts? I'm trying to identify some valve covers I got...mine are 10 3/16" center to center bolt spacing. Thanks. Larry
Not saying it didn't happen, just never seen one in fifty years. Is your cover aftermarket or OEM? Show us some pics. Most likely going to turn out to be Stude, Olds or Y-block. jack vines
I have an early 49 cad engine with no valve covers. I can measure the spacing between the two center bolts tomorrow
