I did the first tune when the engine was in its original configuration that includes SE 266E cams, while I have done the second tune after the SE cams were replaced with S&amp;S MR103 cams. The reason the owner decided to replace, I might add wisely, the SE 266E is due to their poor low to mid-range drivability.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Here is the latest configuration of the Screamin&#8217; Eagle 120R Crate Motor:<\/p>\n\n\n\n<ul class=\"wp-block-list\"><li>120\u2033 c.i.,<\/li><li>10.5:1 compression,<\/li><li>Screamin&#8217; Eagle oversized oil pump,<\/li><li>64mm Screamin&#8217; Eagle throttle body,<\/li><li>5.5g\/s injectors,<\/li><li>S&amp;S MR103 cams,<\/li><li>S&amp;S Teardrop air filter,<\/li><li>2:1 Bassani exhaust.<\/li><\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">The following graph shows the torque\/power values and their trend measured at the wheel on the <a href=\"http:\/\/www.dynojet.com\">DynoJet<\/a> dyno and obtained after a rather complex but adrenaline-filled tuning process.
