I’ve been slowly assembling the parts and getting machine work done on a 6.0L iron block LS-series engine that I found at an online recycling business called LKQ. A couple of years ago, we did a story using an iron 6.0L engine with a set of stock L92 heads, a rather conservative Comp camshaft, a carbureted intake manifold, a Holley 750-cfm carb, and that trick MSD system that allows you to run the stock distributorless ignition. That engine made 550 hp, and I thought if we just bumped the displacement with a 4.00-inch stroke crank, we could make at least 600 hp. That engine is now slowly starting to come together. This will be my first assembly of an LS-series engine, and there are several little things about this engine that are quite a bit different than a typical small-block Chevy. I will be doing a story on this engine in Car Craft, but there are so many little details that it will be nearly impossible to list all of them in the story, so over the course of this blog, I’ll try to drop in the little stuff I’ve learned that may help you when building a LS-series engine. These engines are different, but once you get dialed in on all the little nuances, they’re not that difficult. One of the first things I’ve learned is that the hydraulic lifters on the LS-series engines are an exact carry-over from the ’86-and-later Gen I small-block factory hydraulic roller lifters. I used an old Gen I hydraulic roller lifter to measure lobe lift while degreeing the cam in my LS engine and it worked fine. Now you know, too.
