The gen 5 LT4 engine is the most revolutionary thing GM has given us since the introduction of the LS1 engine! If you're old enough to recall, got GM back to the path of pushing the limits of stock power after the 70s setback and 80s redirection. The LT4 really is the next big thing with the world's only V8 OHV Direct Injection engine, also adding in VVT and also AFM! The heart of the LT4 is a new advanced combustion system that GM spent two full years developing, using their sharpest minds and best analysis tools. Some six million hours of computational analysis (out of the 10 million total hours invested in the whole engine design) were focused on evaluating 75 different combustion chamber configurations. Splaying the valves at an included angle of five degrees, configuring the intake ports with a slight twist, and adding a sculpted surface to each piston top are the most obvious features. Locating the spark plug and six-hole injector and packing in a 54-mm (2.13-inch) intake valve and a 40.4-mm (1.59-inch) exhaust valve inside a 103-mm (4.06-inch) bore were no small feats!
Alas, it's never enough for us horsepower junkies! While getting more MPG is nice, there is a LOT to be gained in those heads and cam! We have several variations of our head and cam options from mild to wild! Our early stage gear will even allow you to keep your AFM if you want! Our weaponX ported heads flow 365CFM at appropriate cam lift and our LTX heads flow 405CFM by .650 lift! The stage 2 and 3 cam kits for this will net you BIG gains over the competition.
While we offer a lot of off the shelf kits we've spec'ed, nothing beats a custom package spec'ed for your build! So, to get a custom WEAPON-X head/cam package, call or email us at sales@weapon-X.com
