400 sbc

this is probably a very stupid question but i dont know and i need to know. i bought pistons of a friend thinking that they were what he told me but they were not and now i dont have the right crank. the pistons are meant for a 3.48 stroke crank and 6 inch rod with a 1.250 comp height and i have a 3.75 stroke crank. i was wondering if anyone knew if this would still work so i could have a 406 or and i going to have to buy a 3.48 crank? or is there anything i can do? thanks Ty.

You could do something perverse like use a 5.85" rod and deck the block, but it would be easier to just get the right pistons.

9" - 3.75" ÷ 2 - 5.85" - 1.25" = 0.025"
