That would depend on what your looking to do with the power plant. There's a big difference in 356HP/426TQ that runs 87 octane and the above 340. The mini stroker also uses more common inexpensive parts like Magnum heads, inexpensive intake and a 600cfm carb. A small MP Hyd. Cam was used. There is a big price difference in the parts as well as a big difference in power.
