Does anyone know who has has success with this engine. I'd like to put one together but I'd like to talk to someone that will point me in the right direction and tell me the steps I need to take.

I don't know how stock engine builders work, but could I acquire parts (block, heads, intake etc) or should I let the the engine builder do it? I'd like to get pieces at time bc I can't afford to just have one built from scratch. But if buying parts over a certain amount of time is ok then I can afford it, but not knowing how engine builders go about building one is beyond me.

Any help would be appreciated
