sae vs metric

[TheOtherNick]

Pretty much everything on a 3800 is metric besides the valve cover bolts.

new cars for the last 15 years or so have all been built with metric bolts, for the most part, that's all makes and models, metric is so much easier to use anyways.

That's not been my experience. Yeah, you could use a 13mm on some bolts, but there is a little play and a 1/2" fits perfectly. Like the dog bones or the fender braces. I don't remember off the top of my head, but I know there were some SAE bolts when I taking the heads off in the junkyard for a top swap. I think they were 7/16.
