1967 Barracuda Formula S 383

In 69 the "HP" motors were orange unless it was in a car with A/C. Then it was still turquoise. Before that I think the only big blocks that were orange were hemis
Do you know where/what numbers on the block would tell me exactly what the engine is?
I know it is a 383 and the build date based on the numbers on the front, but with no vin are there other numbers somewhere else?
I imagine I should probably check the head numbers.
My apologies for asking questions in this thread, but I needed to run with it.

LETS NOT FORGET THERE IS A SWEET 67 BARRACUDA FOR SALE.
That color is killer, nice car.
