variable cam timing old school

[RichSchmidt]

O.K. I will chime in. I always noticed that my old junkyard engines always ran their best right before the stock nylon gear set self destructed. From personal experience,I could guesstimate that the barely intact ones that I swapped out before they failed had a hefty 20 degrees or so of slack in them. Even a conservative 50/50 split puts that at the cam running 10 degrees back during acceleration which is like adding 20 degres of lobe duration without the side effect of additional overlap. It was like a free cam swap. I have pulled out sets that had fewer teeth then a back alley crackho!! [img]<<GRAEMLIN_URL>>/smile.gif[/img]
