still a good thread
durations at SAE (.004 with 1.5 rockers) Crane used to have on their muscle cam, blueprint line but I can't find it>so here is ELGIN E578S
cam lift .286/.296
valve lift .429.444 1.5 rockers
duration 279/289 SAE so compare with Crane/ Cam Dynamics and others that advertise at .004 Summit
.050 209/220
8 37 46 -6 Timing @.050
50 overlap at .050 SAE method
Elgin has a dozen cams for the LA
Elgin Industries
do a spreadsheet if looking for a cam and figure out the intake closing point
other places have the timings at advertised
don't pay for just a name on the box
