At least one owner of an original car noted HIS came with a 427 center oiler. That was a "street" car without sidepipes (under car exhaust). I'm thinking it was one of the very EARLY street cars and shortly after it came the 428's.

Authentic? 390, 427 center oiler, side oiler and 428 take your pic. First 120 or so comp car and S/C cars? 427 side oiler. The S.O. is not really any different than the rest in terms or build or maintenance, just a lot more dollars!

Some will pay more for a CSX number, some will pay more for a side oiler. If I had the money I'd have BOTH in one car!
