I've used FAI parts many times in the past on many different vehicles and have always found them to be good quality. This cam kit is no exception. It's currently installed in my car. Too soon to judge it's longevity but it's doing it's job well enough. If I had to criticise, I'd say the addition of a machined chamfer on the sides of the cam lobes to indicate wear would be perfect. Just be sure that the correct tightening sequence is strictly adhered to, otherwise snapping the cam is a very real possibility.
Bought to replace my worn camshaft and noisy tappets. Seems decent quality for a very good price. It all fitted fine. My car now sounds and drives so much better. Too early to comment on its durability but for the price I am very happy.
