Update with Pictures:
Pulled the engine out the top and tranny out the bottom
Pressure washed degreased and painted the engine bay
Had a little bit of trouble swapping some things over between the motors
COMPRESSION!! WE HAVE IT!! unfortunately the bleeder valve on my gauge started sticking so i couldn't get a picture of peak compression but they were all 500 PSI or higher. New motor spec is 493psi.
New engine even has a block heater in it.
Hopefully have some mpg numbers soon then I can do a few aero mods
