318>390 Stroker.......Your thoughts

If you haven't bought all the parts yet you could consider using a 3.58" crank which works out to about 350 cubes. Apparently it gives a better piston/rod angle for more longevity.
This is what I've gone for on my 318 poly stroker (currently mid build).
I don't know if I've made the right decision or not, maybe I should have just gone all in with the 4" crank, but my goal was a reliable cruiser with a bit more power and torque, time will tell.
