after months of research I’ve narrowed it down to three options 1) buying a 4t3/9 and swapping the r oil pan and head and calling it a day 2) the same as option 1 but swapping in the crank and rods from the 4t4 for the 93.5 mm stroke 3) or throwing k1 forged conrods wiesco forged pistons and the 4t4 crank for a built 4t3/9 with the better 93.5 mm stroke. If you guys could let me know what ballpark hp/tq numbers i could make reliably with each setup that would also be great
