So it’s not a LA after All?

So i’m trying to get started on my 360 build. The date code on the block is 1985, 360 block with 308 heads out of a mid 80’s Dodge Van. However, in a visit with another individual who appears to be well versed in Mopar small blocks, the indication was if the block had a three bolt “spider” bracket in the lifter valley, it would in fact be a Magnum, NOT an LA.

Anyone heard this before?
