Choosing the right stroke for a 340

I run a 340 with a 4 inch stroke and .04 over (418) no clearencing needed.
Ported indy 360-1 heads
Passon hemi OD
4.30 gears.
325/50/15 tires

I have only street driven it.
It takes off like a bat out of hell. When it was just a 340 it took off fast but the torque of the stroker is alot more fun and makes alot of chevies hide.

Now i see the 4.180 stroker kits popping up in places and scratch my head. (435 cu) apparently no clearancing needed
So i decided big block instead ;-)
