rollmaster timing chain sets 350-455. the 455 timing sets have the gears nitrided for hardness and less wear. which is common on the 455. 455 sets 125.00 avail. in .002 and .005 350 sets 116.00 avail in .002 and . 005 avail. soon have 5 sets coming soon.
My advice to you is to try and put the upper gear on the cam, and the lower gear on the crank, before you sell them to anyone.. I just used my first "black" set last night, and there was a whole lot of swearing going on there for a while.. then some machining.. a word to the wise.. rollmaster has been notified. JW
