Can someone help me identify this motor?

[Dodgecharger920]

According to this tag it says
HTB25B
3259 P
12F2T

I'm trying to identify this engine as far as make, hp, and possibly year.

Thank you for any help I can get!

I can't remember what the TB stands for, but it's basically a H25.
2 1/2 HP, early to mid 1960s
