This crank is required for any BP engine that will see sustained use above 8200rpm. The OEM crank flexes too much and tends to cause problems (broken main caps, spun main bearings) under sustained use past about 8300. Also recommended for builds over 400whp. This crank has been successfully used in multiple national championship winning road race engines that see 9000 rpm+. No addtional machining required for crank or block, just have your pro engine builder set up the clearances and drop it in.
