Stroker timing changes ?

So u used the same pistons and rods from a previous build? I presume u used a 360? U have a difference of .420 in stroke. Enlighten us how u accomplished this by not having pistons with a shorter compression distance. Kim
No.. I used a Scat 4” crank , scat rods and Scat Stroker pistons , I should have said that the only change was the 4” rotating assembly.
