TBTW, no one has answered my early Q about the duration of factory cams. Are these duration angles quoted as absolute, or some baseline lift where "real flow" begins? Please advise, thanks!
It is my experience with the A cam compared to the B cam that it flows much more, even though the lift is similar, the duration and LSA differences are real and therefore gives much better mid-range, wider torque band, and pulls above 3000 better than most Volvo cams.
If I were to choose a good cam for the '89 lh 2.4, I would use a VX though, has better low end torque and is better matched for the elec ign that is on that car, i.e. higher lift, less duration and overlap. The A/B cam could use a wider dwell angle to provide more complete combustion across the larger duration of valve opening/overlap.
