I didn't go this year. I saw the photo on Pistonheads. Perhaps I'll make it next year in the Midas.

Abit of a interesting update.

My dad moved the exhaust cam timing on the van yesterday. I had calculated that 1tooth on the exhaust cam pulley was 7.4 degrees.

Now the head on this engine has had a fair old skim so the standard cam timing was retarded. (Don't know by how much thou)

But he says that a massively noticeable difference can now be felt. Feels way more lively and feels more torquey on part throttle acceleration.

Its abit of a bodge but will be taking it back to the rollers to see the difference, but hopefully should be up to stock power now.

about 1 month ago i figured out my motor was in the same boat. both intake and exhaust cams were 2.5deg out (5 crank deg) from 0. not sure about rovers but general rule of thumb for b series is for every .001" skim = 1 degree retarded (crank). i also noticed a boost in low end power.. keep us updated on how the timing helped with the hp.

Interesting that. I've had this problem to on a T16 engine I built. But I guess what you say above will be roughy the same for any engine.

Is .001" a thou ?
