Nothing done to block, forged JE pistons, forged scat crank, h beam rods, cometic gaskets, arp studs, the 501/513 mopar roller cam, 1.7 roller rockers. Not sure on power now, but it runs good, very streetable. I recently went to 3.23 gears instead of the 3.91 that I had, and it seems to like them much more
