ok well i just picked up a set of camshafts that were alot bigger then B16 cams visually. they were in a B16 motor but i cant find any info on who makes them anywhere . at the end of the intake camshaft on the dizzy side its stamped " JM " and there no other markings anywhere on the cams . i dont know much about camshafts but when i held the big ones up to the stock B16 cams the middle lobe out of the sets of 3 lobes was wider in width then a factory B16 cam is this normal for aftermarket cams ? if anyone can tell me who makes these camshafts or what the specs are and if its normal for that lobe to be wider then a stock cam i would really apreciate it ive searched the internet for 2 hours now with no luck thanks in advance

 

my cams have no rings or grooves like oem cams. they look identical to toda B's look wise theres a JM engraved where the B is carved in the toda came
