engine building questions

[riderman329]

I have a LY6 6.0 block being bored out to a 4.03" bore. I bought these pistons http://m.summitracing.com/parts/mle-ls1314030f04,

Orginally I purchased a K1 stock LS stroke crank 3.622" when I was shipped the crank I was sent a 4.00"

My question is will this crank be ok? Is the pin hight being taller gonna be a problem? I realize I'll be going from a 370ci to a 408ci. which isnt a problem, but the main question is will I be ok to use the crank and not have any PTV issues?

Won't work.

A boosted 370 is my original plain, looks like the 4.00" crank is going back.
