Mast Motorsports LY6 HO

Let GM's loss be your gain! Mast Motorsports is offering brand-new-and breathed on-factory truck engines for your hot rod. The 6.0L LY6 V-8 is the variable valve timing version of the LS2 engine, but with the better-flowing cylinder heads from the larger 6.2L LS3. The relatively obscure LY6 is currently the 6.0L step-up option from the 5.3L in GM trucks, and makes about 360 hp in factory trim. The variable cam timing, or VVT, is a step up from previous GM 6.0L offerings too, and endows the LY6 with a fatter torque curve that kicks in at a much lower rpm than older Gen III 6.0L engines, like the LQ9.

In case you hadn't noticed, GM isn't selling a whole lot of big trucks lately, and the warehouse is packed to the rafters with truck engines. That's where Mast Motorsports has stepped in. Mast gets these brand-new LY6s from GM and upgrades the camshaft and springs. Then they package it with their own proprietary M-90 ECM, which they program specifically for the LY6 cam/spring upgrade. (No programming or laptop needed.) If the truck intake is too tall for your hot rod's hood, Mast even offers a low-profile LS3 intake manifold ($500 extra).

Mast calls it their LY6 the "HO" for a good reason: it belts out a staggering 480 hp at 6,400 rpm. And the best part is that Mast is moving these out the door for just $6,995 (part No.: 111-001). The price is turnkey too; you get everything you need to put fire in the hole, including the ECM, harnesses, sensors, water pump, throttle body-even a fly-by-wire accelerator pedal. According to Shaun Lide of Mast Motorsports: "Essentially, when you get one of these engines, it requires power, ground, three wires under the dash, and 60 psi of fuel pressure. Then, you're ready to rock!" We checked around the Internet, and did find other outlets selling bone-stock LY9 crate engines, but they had the factory truck camshaft for a 420hp rating, and the going price was over $9,000.

As GM's stock price craters, so are the prices on some of the best V-8s ever to come out of Detroit. If you didn't think you could afford a brand-new fuel-injected crate motor, it might be time to rethink that logic. While the LY9 "HO" still lags a bit behind the standard carbureted small-block in raw power for the dollar, you can certainly argue that the improved driveability, reliability, and fuel economy of a spanking-new LS engine makes the extra cost worthwhile. And that's an extra cost that's getting smaller by the day.

Moroso Performance
Big-Block Chevy Oil Pan

Make the wrong choice in the oil pan department, and you can expect to pay dearly. We're all in this hobby to have fun, and losing an engine to an oiling problem (or losing a race to a windage issue) is pretty much the opposite of fun. Yet all of us are sensitive to spending unnecessarily in areas that don't need it, so where do you draw the line? Moroso's new wet-sump 6-quart oil pan for a Gen IV big-block Chevy (part No. 21048, $462.39 from Summit) is a great place to draw that line. It's ideal for bracket racers and super stockers, and features a stock rail bolt pattern, a passenger-side kickout with 8-inch rear and 6-inch front depth, a solid louvered tray with main cap partitions for maximum power and oil control, compatibility with 168- and 153-tooth flywheels, and accepts a 4.50-inch stroke with steel rods, or a 4.25-inch stroke with aluminum rods.
