This is a shot of the LSX376 with the MagnaCharger 2300TVS set on top. By combining these two parts with the upgrades and OE replacement parts in this story, our engine will be roasting the tires for years to come. We didn't order them in time for this story, but we also upgraded our alternator and starter with high-output and high-torque units from Powermaster. As a side note, we did learn several important things when we did the swap. The LS3 has a crank sensor in the front, whereas our 4.8L had it in the back. We just extended the wires to make it work and so far, so good. Also, the LS3 has the knock sensors on the bottom of the block, but the 4.8L had them in the intake/oil valley. Again, we extended and rerouted the wires to trick the computer into thinking everything was normal. You gotta love hot-rodding! Making horsepower isn't cheap (as out wallets can attest), but we made the decision to spend more now and have peace of mind, rather than spend less and have an engine failure down the road.
