'69 Valiant 2DR Project

Ok so I went over to my parents to finally take a look at this newer block and I feel like a complete DUNCE!

After some searching and comparing, it looks to me like I have a magnum block. Not sure if this is good or bad yet. I was planning on going with a solid roller setup so I think this may be a good thing? I'm not sure, maybe someone will chime in.




This thing needs cleaned up!
