I guess I will have to get into the 21st century some day soon. I was reading Sept. Hot rod and they took a stock junkyard 5.3 (they thought) from a truck and put some heads on it and bigger injectors and throttle body. It made 451 hp and 380 ft lbs torque in this slightly modified form. They then put a set of twin turbos on it and played with boost. They ended up getting 1203 hp at 26.8 psi and it stayed together. This was a stock used motor (except for the heads). They did like 60 dyno pulls. In the end, they found out it was actually a 4.8. Those LS engines are unbelievable! I just need to wait until they make a plug and play Computer and harness that connects to our gauges ( and is cheap) so an old fart like me could handle the swap.
