What about building a motor yourself? You know for the mechanically inclined person.
You can build your own low HP (1 HP/CI or less) stroker long block for $3600 ($3595). It will be nothing fancy and use all stock based parts. And with stock based parts re-used from original motor. Re-use stock heads with daily driver nothing fancy valve job.
And it's not going to blow up within 1 year.
I don't see why this "Blueprint" company's 408 stroker would be any less reliable than thier 360 motors. Not saying either motor is any good.
It's just a 0.420" extra stroke. If you had a Scat 3.58 crank next to a scat 4.00 crank you couldn't see the difference. But somehow people think Rocket Scientists need to be called in.
