Dan,
I am just finishing up my 393 Stroker for my Everett-Morrison. Most of the pieces and parts, including the stroker kit, I purchased on E-Bay. All in all I spent roughly $1500-1600 for everything. That includes dart heads, pistons, crank, rods, intake,
oil pump, gaskets and most other parts. Aside from any machining, that is relatively cheap. You may want to consider this option for some parts and depending upon what route you take, it may save you some bucks. Let me know if you have any questions about parts and such.
Thanks
Chris
