I recently acquired a '59 Chevy Apache with a 454 Big Block. The previous owner didn't have the specifics of which Cam was installed so I'm struggling with getting this tuned without that info. It's been years since I tweaked engines myself but seem to recall a trick to determine the Cam lobe by doing a vacuum test on the spark plug cylinder.

Does anyone have any suggestions or recommendations for where I can go to get the best resource material for this?

Thanks!
