What is interesting about it? Why would anyone even waste their time and or efforts and also how does it even remotely relate to the average home builder? Home builders aren't able to do the machine work and all the porting and grinding that they will all be doing on that. Anyone that respects their money will spend the same and do a 408 or 416 build and have 50% or more power and torque.......the whole build is pointless in this day and age.
