I'm lookin for the exact specs on the stock 400 camshaft. Anybody know where I can find them? I looked in the specs here on the site but lift and duration are not listed. i'd appreciate it if anybody could let me know.

There are specs listed in the '68 Pontiac Service Manual and the part numbers are listed in the Pontiac Parts Book section 0.519. See:

Sadly, I have found some errors in these books so I often look for multiple references on important stuff just to confirm. Anyway, these might help as a source.

Thanks guys. That cleared some things up. Couldn't figure out how the cam I am looking at was getting .480" of lift, it makes sense that they're advertising total lift including stock rockers. Means I'll be getting those 1.65:1 roller rockers too =D

Hey, that link to classicalpontiac.com isnt working anymore...anybody know why?

Their server is down today ... it will come back up.
