I know the standard stuff: 208/221 duration @ .050", .474/.510 lift, 112 deg lobe sep. But, Dyno2000 wants IVO (BTDC), IVC (ABDC), EVO (BBDC), EVC (ATDC), overall duration.

It doesn't let you put in lobe sep, figures it from the others. Tried guessing, it came up with 108 lobe sep, which made for some high RPM numbers. I've searched the boards for the data, all I came up with was the standard stuff.

If someone has the info, it would be appreciated.

Well, unless someone knows, guess I'll have to wait for the butt-dyno.

I went to cam math and put the figures in there, and it figured it out for me. I have the zz4.cam file if you want it.
