’73 318 engine out of challenger

I have a '73 318 engine out of a challenger and i am wondering if it is of interest to anyone? would this date coding and serial number make this engine desireable..
let me know if you are interested or have an opinion on this motor?

also would like to know if three speed manual transmissions are of value?

please help me if you can.

post mail me here or better yet, email me at garymendy@yahoo.com
