I also have a 2.4T long block so I could perhaps have this machined to take the 2.7 barrels & pistons. I am not worried about producing mega horsepower, just something useable for now

head/cyl stud spacing changed over the years
Stud spacing
964/993 90mm
3.0-3.2-3.3 86mm
2.0-2.7 83mm

An aluminum block will be more stable in the long term, though many mg 2.7s are out there.

If doing a 2.7 mg I'd want a 7R casting to start w/
