Looking for advice all , trying to increase the bhp of the rally KA , are there higher ratio rockers on the market , or whats the ultimate cam for rally use for a 1300 Endura? Thanks.
You can't just go and increase lift, unless you know for a fact there is adequate valve/piston clearance, but a call to piper or kent should help.
tabetha
as above, contact kent/pipe or even newman and get a better cam.
different ration rockers can only work if the fulcrum is moved, and that would be very expensive to do.
