Tweet, that tighter hole is going to have to be homed larger to match the rest. Do you have the pistons yet ? if you have .040 pistons already, and you actually NEED .041 or .042 or .043 pistons, you can do that without customs, and no, I don't mean knurling. Whatcha got ? LSG

Tweet, are you saying the engine RAN with the bores so wildly different ? ! If thats the case, EVERY measurement on the work Jasper did is suspect. I wouldn't trust any of it. And forget about 'kits' - there really isn't any such thing. If you are trying to stay within a limited budget, you should get new ARP bolts for the 351W rods and get a 3.85 crank and look for 302 pistons that will give the compression you want. when you have your new pistons IN YOUR HANDS, the machinist can measure them, THEN the block can be honed.
