'64 GMC engine paint color?

[5Tractorguy]

I wasn't able to find anything thing in the FAQ index so thought I'd ask. Anyone know what color red is close for what GMC used on their engines? I just about have my 305 all buttoned up and it's going to be time for paint soon.

I was going through Eastwood's and was looking at their ceramic engine paint, rated for 650deg. Anyone use this or know how it holds up? I think GMC was a bit more of an orangy-red, this stuff seems to be a really vibrant red (not that I'm too worried about it). Universal Red- Eastwood

Thanks!
