That is a good question. I don't know what spec the current cams are. They came in the car... no markings and are a bit on the weird side. Without dialling them in they caused #2/#4 to run very lean,
and #1/#3 to run very rich. It lead to a great deal of head scratching to figure it out before I had adjustable cam gears. Once dialled in, that problem was solved to a degree, but they are still just bad.
Good power once spooled (at 5k rpm)... but s*** everywhere else. Very sluggish to get off idle... chronic fuel smell at idle... chronic fuel consumption all round. They are not high lift because the
heads haven't been modified to fit them and there is plenty of clearance... but I think they have a moderately large duration and a s*** load of overlap.
New cams are Kelford 199-j... short duration, high lift and almost no overlap. Should be night and day.
