474ci Engine Build - Pump-Gas Poncho Power
|
The rotating assembly kit that Butler Performance recommended for the build includes this forged-steel crankshaft, featuring a 4.25-inch stroke and 3.25-inch main- and 2.2-inch rod-journal diameters. Total displacement yields 474 ci when combined with the 0.060-over 455 block. After threading the ARP main studs into the block and setting the upper half of each Federal Mogul main bearing in place, Otto installs the crankshaft, lower bearings, Pro-Gram main caps, and remaining ARP hardware. The nuts of the four forward caps are incrementally torqued to 95 lb-ft using the supplied moly-lube, while the rear cap's nuts are torqued to 135 lb-ft. Crank endplay is checked and is well within the acceptable range. View Related Article
