One error I guess: Rally Piper ex should be closes at 17 ATDC (57+17+180 = 254)
If 17 BTDC its a 220° cam (57-17+180 = 220)

I agree, the Bentley quotes :-

Exhaust closes 3 degrees BTDC.

Can we get the above table edited?

I have different info on 7A exhaust cam in that it closes later at 3 degrees before TDC not 9 deg as per 3B cam. Everything else spot on.
