Old crane cam help
For anyone interested, here is a chart that I made back in 2005-2006 of all of the Mopar SB cams that were available at that time... I collected data on the most popular manufacturers from their catalogs and online postings and went through all of the information forward and backward... In the process I found some of the information was incorrect, like one spec would not match the rest of the data, so I did calculations forward and backward to find the true specs for the cams and corrected them in this final chart... The spreadsheet goes from columns A to columns BV for the whole spreadsheet, but I collapsed it to make a chart to give all of the corrected information on the different cams...
In this part, you can see the 107.5 for the lobe center on the Crane 272 H10 which I found was the corrected spec and not what Crane listed... This best fits the numbers for lobe center, lobe centerline, and valve open/close...
This chart is the best match for open/close, overlap, lobe separation, and lobe centers.. Not all manufacturers list all of this information, but it can be calculated from the specs that they give in most cases... I do have data from other manufacturers at that time also...Let me know if you are interested in it... But here's the Crane info for now, since this thread was originally about Crane...
