Build, text and photos by Mike Mavrigian . I realize it’s been a while since my last posting of this project’s Part 1 article, but I’ve been tied up with multiple projects at the same time. Since the Part 1 article, I’ve obtained the crankshaft, had the heads finish-machined and assembled [...]
WE BEGIN THE BUILD OF A BORED STROKED PONTIAC 455 TO OBTAIN 501 CID AND ABOUT 600 PONIES.

The center-mounted carb serves as the primary carburetor (P/N 9801), and the front and rear carbs serve as secondaries (P/N 9802). The [...]

WE BALANCE AND BEGIN ASSEMBLY text, photos and assembly by Mike Mavrigian Crankshaft balancing was next on the agenda.
