Finally going back together with a rollmaster timing set and here's my question.
I've heard stories/rumors for years that factory cams or timing sets are 4 * advanced
and can understand if they were taking chain stretch into consideration. Trust that my
105K mile stocker was well retarded with the factory chain That just came out. I'm not
a stranger to degreeing cams but have never checked any stock factory set-ups to really know.
If the Rollmaster keyways/marks are true timing I'm leaning toward installing this at +4*
Just looking for your knowledge/thoughts on cam timing for this stock stage 1 deal.001.jpg
