I have yet to see any of the prebuilt "built" motors last on big power cars. Whereas the ones I have seen done right, seem to hold up pretty much indefinately. Better bearings, a better oil pump (there are a couple out there) and such. All that should be done.
To Ron's credit: I'm pretty sure that's exactly what he does. In fact, I think they use their own in-house piston, specially designed for their Axis motors?
