I can send you a fully sleeved block if interested. It is the only way I would recommend running the stroker. It is about $3,300 to have this done ~ my cost ~ which is why our strokers are costly.
As far as the parts, Tom is a good guy and makes a quality kit there.
Dinan's rotating assembly is around the same cost as that one, and ours is a little higher in cost.
Take that $10k, add $3k in sleeves, a new Vanos pump and solenoids and bearings are another $4,000. You are up to $17,000 excluding the core motor, excluding actually building the motor and tuning and installing.
Not to mention the R&D which costs the most money of all to make sure t works.
This is why when I tell someone I am selling a stroker for $22,000 or $24,000 installed they say I am nuts because dinan charges $50k & they require your perfect core motor in exchange
