Please forgive me if this is in the wrong place. I am going to buy a set of 307 pistons for my upcoming build. All the ones that I see on ebay say the pin height is 1.655. If you look at GM archives they say the 307 has a pin height of 1.675 and the 250 height of 1.655. There are some NOS 307 pistons for sale part number 6271087. Does anyone know the actual pin height of these pistons? I would love to buy the Ross pistons that Tlowe sells but the budget says no. Thanks in advance for any info/comments. Jay 6155
