Default Re: Replacing pistons

OK. step 1). measure the cylinders (all) top and bottom to determine if/ how much taper - wear. A machinist needs to do the measuring and visual inspection. He will be able to tell if it needs to be bored and what size for a complete set of rings and pistons and silv-o -lite are super and USA made. If this is the route taken he will do it and you will have .003-.004" clearance as mentioned above. If you buy inside mics. and a new Sunnen hone you are in $ 1,000 or more and still have to learn how to use the mic.and the hone will break your arm. If it does not need bore and pistons have him measure, hone and supply the pistons. All of this is done with the engine stripped and on the bench. Then valve work & bottom end as needed lifters,guides, timing gears. Short cuts are the long way around. 2). Everyone needs a good machinist even if you have been one. You can't buy the tools and machines for one job. You'd have to sell your house. I appreciate your back ground and experience and you could replace a piston, good luck finding just one - oh the machinist might have one.
