Hi:

You cannot install 95mm P/C's on a 2.7 due to stud-spacing conflicts and issues with the magnesium case.

The biggest practical size for a 2.7 (2687cc) are the 92mm 2.8 (2808cc) P/C's. Larger ones such as 93's are far too thin for proper ring sealing.

I would first establish what performance goals you want and then outline the various options to achieve those objectives. You should understand how expensive a good 2.7 or 2.8 will be, compared to installing a larger engine such as a 3.0 or 3.2. (I have a carbureted 2.8 in my own car, but it was NOT cheap to do).

One simply needs a realistic budget to do this right.
