7 mil build?

[SHIFTx450]

Who's done it? How's the outcome? Where can I get a 7 mil crank? Do best results come with a stock bore? Can it be done with a big bore? Compression limitations?

Only one I know of is the 450 stroker kit from GT Thunder. 7mm stroke on the crank + 87mm 416 custom JE stroker piston = ~450cc's+

It's a torque monster, even with the larger 16T front sprocket I run.
