70's thermoquad 6458S what is it?

I found it in the parts bin. I've had it since the 90's.My Carb# Book shows carbs thru 6457S 400 HP, then jumps to 6460S 440LP. But no 6458S. Anyone have a better book?

Would the last number perhaps be a "3" not an "8"?

If so, it's the same as the one on my 1974 360 Challenger. Carb on my car is the original factory carb.

I'll polish the old carb up, it is possible.Someone here has pm'd for a 6453S. I sold one a month ago that was a 6453S.Thanks!



I think I have too many pans in the fire, too many carbs in the box!
Sorry, it is 6568S. If anyone has a newer than 1974 book, I would appreciate it.
