Hi!
Please, I have a question for all the engine Cooper S experts.
Introd: My 1275 MK1 Cooper S engine was bilt using the METRO MG Cam.
Question: Is it correct to use the standard 160lb double valve springs (7000 rpm limit) or is it more desirable to use the fast road 200lb springs?
Many Thanks
Sandro

Re: valve spring
The MGMetro cam won't rev more than 7000 anyway. Use the softest springs you can get away with. Remember to check the fitted length.
