built xj 4.0 turbo

As you probly have guessed im building a turboed 4.0 board 20 over.....for right now the boost will stay at a "carefully" controlled level of about 8lbs max because of the crap-tastic stock rods....got the forged keith blacks, and clevelite 77s but im worried bout the rods...anyone know what kind of abuse they can handle?

There is a thread over in "Steer & Peformance" with some helpful links, I believe.
IIRC Keith Black or somebodey has built H-Beam conn rods that should do well for a blown & stroked engine. This info is probably in the street / perf section.

As for abuse they can handle... No idea, honestly.
