Do you need a 5-bolt bellhousing?

If you show us the side of your trans, we can easily tell if it's BW or FD.

Nothing complicated here. Very early Mustangs had the 5-bolt. Do you have a so-called "1964 1/2" Mustang? Show us a photo of the bell on your C4. Or the back of the 289.

this isn’t the first anomaly I’ve ran into with this engine. Timing gear was odd had to simply take it to Napa they kept ordering the wrong one and the water pump is slightly different. It’s stamped a 66’ but there have just been som oddities.

Your engine, as a 5-bolt, was definitely built before Change Level 7, which means you need the earlier cam gear, which uses a spacer. Your cam retainer is also different than the later one, but is of course re-used.

You should also have the early aluminum water pump.

When was the car built?

How about that side view of the 4-speed transmission?

so I am not sure what year the car was built the stamp on it says 1966 but I bought it from a guy who took it out of a Mercury Comet. I want to take my 200 6 cylinder out of my 1966 Mustang and replace it with this 289

Yep, that HEH-BW is the same Ford Design "toploader" trans I have.
