SBM "MagnaVelocity" mushroom camshaft.

Just curious if anyone here has ever run or had experience with the only (to my knowledge) Direct Connection mushroom cam offered for small block engines? It's specs are pretty formidable, 324 duration with .633" lift (1.5 rockers) and a 110*LSA. The Mopar Performance books never mention it, but the old DC bulletins list it for NASCAR Grand National use on long tracks and other 355" Kit Car applications. I want to build a 4" crank SB with high compression and W2 heads for a nostalgia build in a really light chassis, possibly manual trans, and I think this might fit the build. I have a new set with lifters, and means to bronze bush the lifter bores, or the tube/peen kit to block the galleys. Any info or thoughts?
