Do you think that i should buy a prepped short or long block from a company like panhandle or coast high with a stroker kit already installed, or should i find a good engine builder around my area and work with him to build an engine i want. Either way i am going to start from scratch with a new engine...i won't be using the stock block, and i will stroke the engine either way. Also what are roller engines, are they stock engines? Plenty Thanks!!!
