A chrome bore and re-lap would result in a better than original methinks.
Perhaps - although I have seen so many messes created by people chroming things that I wouldn't rate the likelihood all that high. But it does illustrate a problem I see all the time - the tendency to jump to massive modifications or perceived hop-up tricks, before even trying basic simple things like breaking it in fully. We were beating on the piston with a big hammer a few posts ago.
This all on an engine that was once offered for $4 on a bubble pack card, and for all we can tell, is performing pretty much like it was intended +- the usual variation.
Bear in mind I am just providing suggestions, as you are. They aren't commandments, anyone can do anything they want. But if you wanted something better than an original stock McCoy, I can think of A LOT better and more effective ways to spend your $100 or so.
A far more effective method of improving the performance is our old pal, Vitamin N. It will blow in rather short order, but anything you do to get 33% more power will have the same result. Or we could have someone make a new crankshaft and conrod, too.
