This is why I am doing the turbo before 4L80E transplant. It only adds 50 Hp but nearly 100 foot-pounds of torque. Engine torque curves track volumetric efficiency curves. Adding a turbo only changes charge density, the volumetric efficiency remains the same. Power is based on mass flow rate.

The injection pump in my 1031 is the DB2829-4520, calibrated for 48-52 mm^3 (microliters) per stroke up to 3600 RPM. It still delivers 40 mm^3 @ 4000 RPM. The problem is the engine breathing above 3600 RPM. Which means higher EGT and decreased thermal efficiency. Earlier pumps have similar...

GV OD would work on a 1008 but 1010 and any towing application would lose considerable energy in torque converter slip. Yes, the 4L80 requires electrical logic for full automation. It can be manual shifted via simple switches. With aftermarket controller, it is quite simple to get a modern...

The governed maximum speed of the engine is debated often..per the calibration on a DB2829-4520, the pump delivers maximum fuel of 48-52mm^3 at 3600 but still delivers 40mm^3 at 4000 RPM. At 4400 RPM, it should be nearly nothing @ 8mm^3. Since this is the pump in my M1031, I can attest it will...
