==== Cams ==== On US models, you should swap the stock 107 intake cam with the higher lift 104 cam. This does sacrifice a little power at the low end (below 3k RPM) for top end performance. ==== Cam Gears ==== {{:engine:cam_gears.jpg?400|}} ==== Cam Follower Shims ==== It is very possible, after an engine rebuild, that your valve clearances will be off (the distance between the cam and the follower). They should be 0.005 - 0.007" for the intake and 0.010 - 0.012" for the exhaust. The shims can be purchased from a Lotus parts dealer, but the same shims are used in other engines. The shim diameter should be between 0.61" - 0.63". * Saab 99 * Triumph Dolly 1850 * Triumph Dolomite sprint 2000 * Triumph TR7? * Austin Maestro 1600 * Jaguar 6 cyl (Mk II; XJS; ...) (diameter the same?) * Lotus Elite (also a FeatherWeight?) * Lotus 900 series * Rover 2000, SDI * Audi 5 cylinder.
