With the last carbureted cars in the United States falling under Model Year 1990, it would seem that fuel injection should have a stronger presence in the aftermarket. Yet often we hear of the downsides of fuel injection and the advent of the carburetor from hot rodders who look down on fuel injection as too complex and expensive. Even with companies like Holley cranking out plug and play systems, there are still detractors that are all about a 750 double pumper on a stout intake manifold.
Enter Engine Masters. David Freiburger, Steve Dulcich and Steve Brule are tackling this issue head on in this episode. The lump on the dyno is a Chevrolet LM7 5.3 LS motor, a crate “327HO” block. Stock, these were advertised at 327 horsepower and 347 ft/lbs of torque. For the test, we have two options: a Holley 750 and a Holley Terminator EFI kit. Brule seems to gravitate to the carburetor, Freiburger is familiar with the Terminator system, and as for Dulcich…well, he’s a Mopar guy staring as an LS motor on a dyno. Who wins this round?
