11.6mm lift hollow billet lightweight camshaft with 284 degrees duration at 0.30mm tappet clearance (253 deg. at 1mm lift). Designed by leading UK Alfa competition engine builder Jim Evans, whose experience and knowledge is second to none, this is an excellent inlet or exhaust cam for race / trackday 1600/1750/2000 engines. Combine with camshaft EN521 on the exhaust or another EN522 for a great combination, particularly good on 1750 engines. The advantage of this cam is that it can be used with standard piston cutaways. As with all camshafts with lift greater than 11.4mm it will usually be necessary to modify the cam follower housing to fit this camshaft. Made in EU by very well respected camshaft manufacturer who supply many leading European race preparation companies.
Price is per camshaft.
Please note that with all performance camshafts (with a lift of more than 10.8mm) it may be necessary to make a simple modification to the shape of the cylinder head around the camshaft follower to allow the camshaft lobe to turn freely. This is particularly an issue with early (pre-1972) heads.
