Hi.
Please advise how to identify these numbers on my Mopar 440 block, or just confirm what they mean.

- Pad: 6T440E
- Block: 4006630-440-3
- 2 - 4 - 1976 (I assume it is date of assembly = 2. april 1976)

and advice or refer to experience if a suitable bellhousing, clutch etc. are available to mate up the motor to a NP435

Thanks.
