[My427stang]

I am restoring a previous replica ERA S/C with primarily track use in the past to a period correct street beauty.

I have read some of the past engine color discussions in this forum and want to make sure I got it right, as well as ask a question about the expansion tank

1 - I understand that the real S/Cs were built a bit later, would have a blue engine because of that. Is it the same blue as a later CJ? Would there be blue 427s too in that timeframe or were all the blue ones 428 powered?

2 - Does the intake mounted expansion tank get painted blue or black like other 427 Fords? The car I have now has it painted engine color (blue) but it looks odd to me.

Thanks in advance
