Perfectly Done DATSUN TURBO "Playing Possum"

Old School Datsun TURBO with new drivetrain, "Playin Possum"
This was one of the vehicles that drew my attention the most, and it was at the very end of the day, after I had walked about five hours.
I liked it so much that I decided to record a short video.
Please let me know, what engine is that?.
This was recorded at the 50th Daytona Turkey Run
Thanks for watching :)
Lincoln
ps. I did not see anyone around the truck to get more info.
