Does anyone have complete data for a stock M20 camshaft?

I need the lift per angle of rotation (or as small increments as possible) for a stock cam.

This is what I need to fill in as part of my engine model for my university dissertation:
M20 Blank Cam Data.jpg
So not just maximum lift and total duration but the lift for a full 360 degree of cam or 720 of crank.

& if anyone knows what the positioning/timing is i.e. IVO at TDC


Thank you! :)

Looking for something like this? https://www.r3vlimited.com/board/forum/ ... nd-rockers
Yes pretty much exactly!

I manged to get my spare cam measured by Spring Engines in Rugby and very knowledgeable guy.

Now I just need to know what the factory cam timing specs are in crank degrees compared to cylinder 1 at TDC.
