newby needs engine id help!

[64 inboard]

I just purchased a 1964 Correct Craft inboard ski boat with an inline 6 Ford engine. I think its a 63 motor. Im trying to find out what c.i. it is. The intake is cast into the head. The block has a casting #C3DE6015-E. The head has a #D3DE-6090 AA.

It has poor compression in one cylinder. Before I tear the head off , I would like to find out what I have. Anyone know? Thanks!

Sounds like you have a Falcon engine. If you post this in the 144-250 small block six area you will probably get all the information you need.
