Stroker 440

Wondering if anyone can chime in on a stroker 440. Which one ? Any issues? Where to buy the stroker kit? Just wanting some input. Thinking about building one this winter and replacing my 440

400 block can go as big as you could ever need. They have the biggest standard bore. They have shorter cylinders which makes them stronger.

The main webbing is stronger. The main diameter is smaller leaving more meat in the mains.

The 400 block is the strongest factory block period.
