No, the Hemi is a new World Block casting, its bored 4.5" and has a stock deck height. It is the latest design block for the late 60's hemi. TimNice car!!!! Is the hemi the original motor?
My first car was a 1968 Roadrunner. Bought it new. Had a 383 with a 4 speed. The hemi option cost ~$800. Wish I'd got the hemi! Would still have the car if I did.

Didn't realize you could buy replacement sheet metal panels to repair all the rust damage. Bodywork had to be a couple years work.
