Anyone know the ring gap, standard bore, stock piston with Enginetech cast rings?
Ring manufacturers for stock OEM rings will be at about the max, and if the bore is worn out, it WILL be even worse (larger). Yes, larger is better than smaller, but a stock ringset will never be on the small end. Now, a file to fit set will be smaller and will require filing to the required gab, but the OP referred to a plain jane OEM set of rings, not a HP set. And yes, most domestic old school engine specs will be 0.010" to 0.020" or 0.010" to 0.022". Don't believe me, reference a shop manual...The old rule of thumb is 3 thousands per inch of bore.
Always check your ring gaps. If they are too big - nothing you can do about that.
If they are too small - the engine will give a big problem pretty fast.
