I like them. Some guys here poop on them because there's been no "real" high hp build allegedly like some W8/9's have been built to. Reliable 1000hp capable blocks from a wrecker yard, junkyard heads capable of 400+ cfm when ported (Apaches, you can buy them complete for about $800 a set off of LXForums), factory hydraulic lifters good for 7500 rpm. Only real short coming is the factory valvetrain (that you can get out of any junkyard from a Ram 1500) is good to "only" mid .650" lift before it starts to get sketchy lol. Manton brought out their rocker system that they claim is good for .850" of lift with stock valves but it's $3500. Pricey yes but how much is a rocker system for an LA capable of .850" of lift going to set you back? Maybe not $3500 but it's going to be in that stratosphere. Guys cry about how expensive cams and intakes are, but to get LA stuff that's as capable as junkyard Gen III parts is going to cost you a lot more (do they even make an aftermarket LA block now?)

Not hating on the LA/B/RB, but some of the complaints of the Gen III border on comedy
