Re: Stock versus Performance Cams
Zephyr springs isnīt that much tougher then the stock springs...i can measure a couple but if i remember right in the 60lbs neighbourhood...
Then there`s a lot of different things sold as "Zephyr" springs out there...
Stock 40lbs-Zephyr 60lbs-185G 85lbs...coarse estimate without any warranty...
