       Title Page:

       Carburetors can deliver very good results as did this BLP 4150-style carb on the street 565 engine shown here. This unit used a Dart block, with heads and intake by Brodix. Built by Throttle’s Performance of Argusville, North Dakota, this 496 cranked out a civilized 700-plus horsepower. The question we are asking here is: What would it have done if spec’d for EFI?

       Top Left:

       Short of a supercharger or nitrous oxide, tapping into the big-block Chevy’s displacement potential via a stroker crank and bigger bores is the best route to high-torque output.

       Top Right:

       Reshaping the combustion chamber yields performance benefits. To keep the exhaust flow from going into reversion, I cut the chamber wall flatter in the area indicated to move the quench pad farther from the exhaust valve.

       Bottom Left:

       If you are doing a serious engine build, port matching needs to be part of your build-up plan. Note the wraparound safety glasses, ear protectors, and face mask. All are important safety equipment, so be sure to use them.

       Bottom Right:

       I use this Moroso degree wheel. It is one of the biggest you can get and is just right for timing in a Chevy big-block cam. It is also unique because it requires no calculations to get the cam’s degree setting in the engine. The setup here is being used to check out the rocker ratios of various designs.
