I don't want to steal this thread but I would like to know how to wire a "Bump Switch"??
I always have to have someone help me turn the engine over with the starter, it just doesn't turn by hand unless I remove all the plugs.
The cam company spec. give you a arrange for ajustment(.020 to.025) but as some else said if you have an iron block and aluminum heads like I do, you will want things a little tighter(.012 to .015).
I always try to do one bank at a time adjusting the valve as the other one become active.
I have done it hot with the engine running but not in the cobra. It takes a week to clean up after that type of adjustment. Sometimes that is the only way to get your hands warm up here in the Northeast. Snow again today
