I could not find many shelf pistons in that bore size, summit has some JE in that size and the price of those compared to the BME would of been pretty close. In fact we are going to use the JE rings because it was hard to find rings for the bore size. I also went with BME because it is nice to do business face to face and like to support local businesses when possible.

well i just did a 4.580 bore bow tie block. the guy had the pistons so i bored and hone his block and rings are $$ and from what he told me that JE is the only one that sells the ring s ? hard to say i never look in to it for him but told me top rings are $20. each.i told him to look in to a total seal rings as in the past they have had off size bore rings . any ways i would of used a 4.600 bore piston i do not know what chamber you have but i sure something could of been made to work less you have a odd size rod and stroke
