Engine build April 25, 2021, 07:54:37 AM Currently building a 2.0 8v engine with big valve pb head ported and polished agg bottom end will also be fitting a newman 272 cam once engine is in and running just wondering as its states on the newman site that can be used with original cam pulley is there any benefit from using an adjustable pulley or would standard be ok to use
