74 challenger please help!
I recently purchased a 74 challenger and I got it running today but there’s a slight issue. There’s coolant coming out of the overflow valve and I’m worried it could be due to a blown head gasket. The car hadn’t ran for a year prior to me owning it, there’s no visible coolant at the top of the radiator so I’m thinking it might be some leftover before it leaked out, my oil isn’t milky from what I see, and there wasn’t a lot of white smoke coming from the exhaust when I started it. Just hoping if someone could help me diagnose this, thanks!
