Man all this valvetrain failure talk has me thinking you should just take merc lobes and widen them. Would be nice to have peace of mind from knowing the cam combo did an endurance cycle at some point.

If you want to use your current pushrods, you'll need to have same exact base circle as your current cam. Having a cam reground removes material, not adds it, so you'll have to re measure for new (longer) pushrods. Just a heads up.

It might have pulled a couple hundred more rpm with a bigger carb, but it was peaking at 5500. [ATTACH=CONFIG]551503[/ATTACH]

I didn't mean use the same came. Just the same ramps but widened, on a new cam. Going to bigger dia cores and scaling the whole deal actually would be best.
