That is sweet too bad the small block mopar and the big block dont share the same bellhousing patern, those R154 are known to handle 900hp with the Marlin Crawler upgrade kit that consists on a billet bearing bracket a trust washer and 1st to 2nd billet fork, i got one of them that was behind a 1000+hp 2jz supra engine that ran 8.45 in the 1/4 and still in good shape.
