Dan did you have L2 or CPL2 cams - The L2 cams were a longer duration approx 300 degrees and 0.35 cam lift which gave more top end but lacked mid-range torque compared to the QED 360 / Lotus D type Sprint / CPL2 cam which are all about 270 degrees and 0.36 cam lift ( 0.35 valve lift) and all should give essentially identical performance.

Mine were L2. I don't have the specs handy (in Cayman Islands rights now), but QED's website is very good, or you can always call. They have very good service. Mine arrived in USA within a day or two of being ordered and postage was reasonable. All the bes, Dan

When I initially looked into this it was the cost that put me off. But if I had the money I would get some QED 360 cams. I have had the pleasure of driving a plus 2 in a similar state of tune to mine but with these cams fitted. So much more torque and all through the revs too. Id like to drive a big block 420 spec as a comparison but at about ?1500 possibly more these days, and thats just for the top end, its a little steep for me. It really makes the zetec conversion look value for money.
I know it doesn't answer the current questions being asked with reference to cam specs. To get these I looked at web sites but strangely enough I didn't get QED specs.

All I can add to the recent thread revival is the QED 360 spec cams in a standard but fuel injection equipped twink is a pretty good bet.

For interest i have added a couple of pages from my '75 notebook. Obviously the QED notes in red were added later, about nine years ago.

Yours differs from what they are putting out now (MOPs of 100,106 ) as opposed to 105,110..

Jets etc...

as for the second sheets I have downloaded them but can't make them out...

For me I just click on the image and it magnifies.

Or is it my scribble that you can't read? :oops:

It was just for interest. I wouldn't rely on it, especially the likes of the machining to be done on the spring pockets (first page far right in red). I seem to have two dimensions for the L1 and L2 lift as well???
