Hey guys, first post in a long time! Been real busy with work and life and what not. Been working on my latest project in the building of my 79 drag car by doing a little engine retrieval. Pictures below of the mayhem I caused to the front of an RV in order to get said engine https://1drv.ms/u/s!AnhcUvYxpNLNiwKx1Q6rx1uZbXL9 https://1drv.ms/u/s!AnhcUvYxpNLNiwOiOwbsCHbJCGGR So The engine pictured is a big block 454 with casting 14015445. This tells me, if I'm not mistaken, that this could be either a 2 or 4 bolt main. My question for the more experienced guys is would there be a way, short of pulling the pan, to identify this engine as a 2 or 4 bolt main before pulling it? I'm going to pull it either way, was just wondering.
