Anyone Got Specs For Stock CAM In a 70 350???
Does anyone have the specs for the stock cam in the 350 in 1970? What I would like is to have the duration, valve lift, and lobe seperation if possible. I want these numbers for comparison and because i would like to know so i can maybe set it up in Desktop Dyno. Thanks

These were the specs I looked up once for my old cam when I pulled it out.
.390 Intake .410 Exhaust 310 Intake duration 329 Exhaust duration 1.5 rockers I don't remember the lobe seperation, probably 110.

70c10 - where did you get the #s for the intake and exhaust duration? They seem to be really high. Higher than the performance Comp cams im looking at. Did u mean 210 intake and 229 exhaust? cus that would make a lot more sense. Thanks

Gm lists the advertised duration different than the cam manufacturers, making it hard to compair. The dur @ .050 on that cam is 195/202....really pretty tame. It should be on 112 lobe sep angles......crazyL
