You ain’t screwed. Like I said, don’t fixate on the cam. That’s the least of your concerns. Put the cam and lifters on the shelf and turn your attention towards the foundation. When you get to what an ideal cam would be then it’ll all make sense.
We all have bought parts akin to putting the cart before the horse. Dopamine highs run amuck. Worse case scenario is you sell that cam, lose a little cash but ultimately you get the ideal one. So you lost a little money in the ordeal. Big deal. We’ve all been there.
Keep an open mind, the guys here will steer you right. :)
