I guess they got different timing and maybe liftslopes too tho?

So even here it can be seen that different designers have different idea's as to what cam profiles are best suited to the Cosworth engine
Piper cams told me the best cam change for the cossie (and most popular apparently) is the BD14 inlet and BD10 exhaust.
Piper cams are wrong if they claim that. It may very well be an exellent choice for a standard´ish engine, but BD14 and BD10 just can´t be the ultimate cams for all cossie engines.
