thanks for your input jon, yeah not sure at this point what pistons / rods/ crank, i would use for a stroker, might even go a custom H-beam rod if i was doing FI. but yeah I am still doing my homework... keep in mind we have the 3.2L s50 as well so that may be the preferred option, i'll have to look at cost, may just opt for a stroker without FI. but i really like the stroker idea especially since s50 engines will be expensive to find in australia
