The connecting rods retain the 6.098-inch length of other LS engines, but they are not interchangeable. In order to accommodate the longer stroke with the stock 9.240-inch deck height, engineers made the wrist pin diameter smaller compared to the normal Gen V LS pin diameter of 0.927. The L8T wrist pin diameter is smaller yet at 0.863-inch. This was done to allow the standard rod length while avoiding the issues of the wrist pin intruding into the oil ring while still clearing the counterweight with the piston at bottom dead center.

For performance applications, SDPC has created several forged piston and 4340 steel connecting rod combinations that can push this engine to the next level. SDPC has already built and tested a 14:1 compression competition engine with a solid roller cam using a SDPC race version of the L8T block that makes 860 horsepower at 8,000 rpm with ported LT4 heads and port fuel injection using a Holley Hi-Ram and Dominator ECU.  This image shows the location of the arrow-shaped piston oil squirter bosses at the bottom of the bores that will aim upward so shoot cooling oil onto the back side of the pistons. Moving on, Fowler told us that one area that is of concern for higher rpm applications is the L8T’s variable volume oil pump. In the quest for more efficiency, GM designed a pump that varies the volume and pressure with the use of a solenoid that can move the position of the center portion of the pump. At idle, low rpm, and low load situations the volume and pressure are reduced. The problem is that above 5,500 rpm these pumps begin to suffer from cavitation, which introduces air into the oil. This is partially due to the fact that the pump is driven at crankshaft speed while older engines like small- and big-block Chevys used oil pumps driven at half crankshaft speed. According to Fowler, SDPC’s own testing has revealed the stock pump fails to supply sufficient oil at loads above 1,200 lb-ft. Obviously this is not a problem for a typical street engine and SDPC is working on at what levels of normally aspirated power and rpm will dictate changes to the pump. This is why SDPC’s own twin-turbo engine is fed with an externally-driven oil pump. Direct Injection intake ports are huge and designed to flow great quantities of air with nearly a direct shot to the back side of the intake valve. This is a ported LT1 version but illustrates the concept. Direct injection also means these Gen V heads feature a fuel injection nozzle in the chamber opposite of the spark plug. The nozzles are fed from a high-pressure pump located at the back of the engine on top of the lifter valley cover in a similar fashion to the other direct injection engines. The high-pressure pump is driven off a tri-lobe arrangement at the back of the camshaft. The L8T heads are similar to other direct injection heads. One feature of the Gen V heads that is not commonly known is that the engineers reversed the order of the valves compared to the Gen III and IV LS family of heads. The older heads placed the exhaust valve at the front of the head repeating an exhaust-intake pattern. The LT engines reverse this placing the intake valve forward repeating an intake-exhaust sequence. This of course, also changes the lobe arrangement on the camshaft. The L8T heads offer an ever-so slightly larger combustion chamber compared to the other LT engines. A typical LT1 chamber is 59 cc while the L8T measures just over 60 cc. Since this engine was designed for 87 octane fuel use the lower compression likely involves a slightly deeper pocket in the piston. This combination drops the compression ratio to 10.8:1 compared to 11.5:1 for the LT1. The L8T heads, like other Gen V heads, feature amazingly large intake ports with nearly a line-of-sight to the intake valves. Valve sizes are also the same as the LT1 with a 2.126-inch intake valve but SDPC engine builder Kurt Urban tells us the exhaust valve is made of Inconel, which is a material that’s stable under high temperature. This material makes it perfect for turbocharged use. The valve angle also remains the same as other Gen V engines at 12.5 degrees. The exhaust port on all LT engines which includes the L8T, offer raised exits to drastically improve exhaust port flow, allowing hot rodders to make amazing power even with relatively short duration camshafts. The selection of intake manifolds for the Gen V family of normally aspirated direct injected engine is substantial so there should be opportunities for swapping a more performance related intake onto the L8T engine. The intake manifold bolt pattern retains the same configuration as its smaller displacement cousins along with its 87mm drive-by-wire throttle body. One interesting note on the L8T truck engine is that because it is used in a heavy-duty application the accessory drive employs two alternators, placed on opposite sides of the drive assembly. It’s unclear at this point if a single alternator L86 accessory drive could be used in its place. It also should be noted that all current Gen V engines do not employ a hydraulic power steering pump but there are both Chevrolet Performance and aftermarket kits available to add hydraulic power steering to a Gen V accessory drive.
