Build a 740hp Big-Block Chevy in Your Driveway
We hauled the engine to Westech Performance Group for testing on the Superflow dyno, and technician Steve Brule made sure the engine was tuned for maximum effort. After a few pulls to make sure everything was in good working order, Steve played with the engine's ignition timing, valve lash, and carburetor jetting. The final tune-up, which netted the best numbers of the day, was as follows:
* 1-inch carb spacer
* Jets: primary: 82; secondary: 82
* Total ignition timing: 34.5 degrees
* Valve lash: intake: 0.010 inch; exhaust: 0.016 inch
* Exhaust: 2-inch primary tube headers with 3-1/2-inch collectors and Flowmaster mufflers View Related Article
