340 or 408?

Cool. What did your 4” engines run and at what weight? Fuel?


None of them are mine. Again, I don’t do 4 inch strokes.

You aren’t an engine builder so take your dick measuring contest somewhere else.

Just for you, my first 408 in 2000 went 540 hp at 5200 on a hydraulic roller.

With a mild solid roller at moving peak power to just 6k would have put it over 600 hp.

And it’s STILL a tractor engine.

The stroker guys all pee their pants if you even suggest all that stroke doesn’t mean **** without rpm.

Unless it says John Deere on it.
