Roller cam & lifters Nige, usually comes in a kit

You need to buy the conversion type roller lifters with whatever type cam you choose, not the factory rollers. Real Steel do a selection.

Cam, lifters, decent timing chain, cam button to limit walk as roller cams try to push forward out the block. If you dont get an iron distributor drive on the cam then a bronze or composite gear on the distributor (be prepared to change it every 6-8 thousand miles). Possibly a new set of springs too and maybe pushrods depending on what lifters you buy. No point getting roller cam, roller lifters and running stamped steel rocker arms either so a set of branded roller rockers. DO NOT buy no name cheap roller rockers. In time the needle bearings will fail and you will have them all round your engine. I've seen it 3 times now, it's not pretty and it negates the short term saving having to rebuild the engine. Get a good set like Crane, Comp Cams, Erson, Harland Sharp, Lunati etc. The last items you may have to buy are taller valve covers to clear the roller rockers.

Try Dr.Dee (fastcoauto). I have just fitted one of his roller cam kits with the warhammer rockers and very happy:D loads of torque all through the rev range. I was using a comp cams 280h magnum camshaft which was good but the roller has a far better rev range and the power delivery is superb, I am now looking for some new rear tyres :D:cool:.
Well worth talking to, nice guy.
