The engine now has an Edelbrock intake and AVS2 carburetor on it, and the original computer stuff is long gone.  There is an MSD ignition box connected that controls the spark firing and timing.  I wasn&#8217;t sure if this was still operational, so I hooked up the power and plugged in a notebook computer.  MSD supplies an application for the notebook that lets you configure the MSD box and see any error codes that are stored.  Luckily the MSD box seemed to be healthy and ready to go.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">As part of the wiring prep, I removed 3 control wires I am not going to be using, tach, and launch control rev limiter.<\/p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"alignleft size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"768\" src=\"https:\/\/www.bracketracer.com\/wordpress\/wp-content\/uploads\/2025\/06\/IMG_5054.jpeg\" alt=\"\" class=\"wp-image-1458\" srcset=\"https:\/\/www.bracketracer.com\/wordpress\/wp-content\/uploads\/2025\/06\/IMG_5054.jpeg 1024w, https:\/\/www.bracketracer.com\/wordpress\/wp-content\/uploads\/2025\/06\/IMG_5054-600x450.jpeg 600w, https:\/\/www.bracketracer.com\/wordpress\/wp-content\/uploads\/2025\/06\/IMG_5054-768x576.jpeg 768w\" sizes=\"auto, (max-width: 1024px) 100vw, 1024px\" \/><\/figure>\n<\/div>\n\n<div class=\"wp-block-image\">\n<figure class=\"alignleft size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"768\" src=\"https:\/\/www.bracketracer.com\/wordpress\/wp-content\/uploads\/2025\/07\/IMG_5308.jpeg\" alt=\"\" class=\"wp-image-1513\" srcset=\"https:\/\/www.bracketracer.com\/wordpress\/wp-content\/uploads\/2025\/07\/IMG_5308.jpeg 1024w, https:\/\/www.bracketracer.com\/wordpress\/wp-content\/uploads\/2025\/07\/IMG_5308-600x450.jpeg 600w, https:\/\/www.bracketracer.com\/wordpress\/wp-content\/uploads\/2025\/07\/IMG_5308-768x576.jpeg 768w\" sizes=\"auto, (max-width: 1024px) 100vw, 1024px\" \/><\/figure>\n<\/div>\n\n<div class=\"wp-block-image\">\n<figure class=\"alignleft size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"768\" src=\"https:\/\/www.bracketracer.com\/wordpress\/wp-content\/uploads\/2025\/07\/IMG_6712-1.jpeg\" alt=\"\" class=\"wp-image-1600\" srcset=\"https:\/\/www.bracketracer.com\/wordpress\/wp-content\/uploads\/2025\/07\/IMG_6712-1.jpeg 1024w, https:\/\/www.bracketracer.com\/wordpress\/wp-content\/uploads\/2025\/07\/IMG_6712-1-600x450.jpeg 600w, https:\/\/www.bracketracer.com\/wordpress\/wp-content\/uploads\/2025\/07\/IMG_6712-1-768x576.jpeg 768w\" sizes=\"auto, (max-width: 1024px) 100vw, 1024px\" \/><\/figure>\n<\/div>","protected":false},"excerpt":{"rendered":"<p>This engine originally had a computer-controlled EFI fuel system on it, which also controlled the ignition timing.
