my end of it - it has a cone and knuckle heads and knuckle lifter blocks soo its a solid cam - but the rocker arm ratio is 1 to 1 knuckle and cone shovel 1.53 evo cone 1.625
knuckle lifter blocks have a drain back hole into the top of the engine block that goes to the breather valve gear end, the breather gear has a timed hole that sucks the oil back into the engine, pumped into with the external oil lines shown, via the special hole in the breather valve cavity - some smarts have gone on to make this happen -
what they did to evacuate the top end of its excess oil is an interest to me
so the knuckle stock cam lift is .390 @ 1to1 ratio the heads wont take a shovel lobe much less a evo lobe coolstuff
so the camshaft is a made for the job - as the S&S knuckle cams is only .420 lift lots of duration interesting machine
