Hi Bruce, sorry I can't answer your question, I just wanted to let you know I have a similar post not to far down from this one.. subject is something like 'timing set selection'.I'm actually going to be running the TFS-51402001 cam, which has about .351" lobe lift(.563 @ valve w/ 1.6:1 rockers). I plan on running that retro conversion as well.. hopefully it will work alright. What are the specs on your cam? I think you can run your typical dual roller timing set without any problems. You could always call up summit support too to see what their opinion is. This is the one I plan on picking up, which should work well for you too. http://store.summitracing.com/partdetail.asp?part=FMS%2DM6268A302

You need the chain set for a '69 351w. The cam or crank doesn't matter.SteveW

The H.O.'s had no fuel pump eccentric and fastory roller cams. Your '69 351w isn't a H.O.SteveW

You should be fine with the set I mentioned above Bruce. Under application, it mentioned 351w, and even mentions requiring the eccentric under technical.
