Is It The Original Engine?

[tera155]

Having found out my 66 has a 68 Eldorado transmission. I thought I should do some detective work on the engine.

Also I have been told the color of the engine is not original. Any advice on checking various numbers on the engine to determine if it is original. etc. welcomed. Below is a lo-res photo of the engine. Thanks, Thad Dupper, Colorado

Having done some more work I found:

The engine unit number from the engine tag behind the alternator as: N 624834 T

The Block Casting Number (behind the water pump) of: 389244D

On either head the casting number looks like: 389 896 (it could be the starting 3 is an 8 -- hard to tell).

Each head has a B on it too.

B heads are for 66 Toronado only, yes those are correct. And the block casting number is correct.

Head casting number is 389395

I believe your engine unit number is correct for Toronado 425 engine.
