Product Information

Gold Label Premium and Red Label Timing Sets: Rollmaster and Romac are household names for products that fit the first time, work exceptionally well and give the installer a better return on investment without claims. Products that sell themselves All timing sets are produced using billet steel for both the crank and camshaft sprockets. Material grades are mentioned further down the page. Gold sets are nitride hardened and include a one-piece Torrington bearing with an Iwis chain. Timing chain sets have 9 keyways unless otherwise stated. Smaller bores tend to be best suited to 7 crank keyways, although engines like Small Block Chevrolets etc. come with 9 keyways which allows more adjustment for dialling in the cam. Crankshaft sprocket keyways are in 2-degree increments unless otherwise noted. The relationship from crank keyway to camshaft sprocket timing is 2:1 meaning that the amount of advance or retard at the camshaft is in one-degree increments, IE 1, 2, 3 or 4 degrees. Multiple keyways are a solid fixture and do not tend to move or work loose like offset dowels, thus providing a positive locking of the cam timing to what ever position is desired. Rollmaster timing sets are light weight and stronger than any other timing set available, due to the weight savings of billet steel and use of CNC machinery. All Red Label timing sets come standard with our own premium grade one-piece Iwis full roller timing chain. Every small and big block Chevrolet comes standard with a brass thrust washer. You will find Rollmaster has included brass thrust washers to most of our range including Ford for increased performance and reliability. Most Gold Series timing sets have a one-piece Torrington thrust bearing fitted and all have both sprockets nitrided. There is a very comprehensive range of Gold Label and Red Label sets. Line Bore Sets: We can supply .002” - .005” - .010’ oversize sets. The oversize is added to the part number as CS1000 – 010” which is ten-thousandths oversize. When a car has been Line Bored you will need to fit the correct oversize set. The sprockets are made larger to take up the chain slack. Most of our Sprocket sets are available in Line Bore sets and this often gives us an advantage over our competitors. Nornda Automotive have been running for 25 years and you will find us flexible with most products as we can produce new items that would sell repeatedly given samples and quantity sales volumes.
