302 valve timing

[67rcks]

What are the specs of stock camshafts used in 302/5 liters?
I guess there ain't too many of them.
i.e. start and duration of intake and exhaust at .050, valve lifts
Anyone knows?

I don't know the answer to your question, but there were several different cams depending on the year of the engine.

If you are refering to the original 302 (non-BOSS) engines used in the classics, they are .368" Intake @ 184 degrees and .381" exhaust @ 189 degrees.

those degrees are (most likely) duration at 0.05? for lobe centers it would be too late I guess. Did you have luck finding a complete list of 302 cams specs?

Well in the '70s they went to a .381" Intake @ 183 degrees and a .395" exhaust @ 192 degrees. The next significant cam is when they went to the 351W passenger car engine camshaft for the 1982-1984 (1985 Auto) 5.0 HO engines that use the 351W firing order.
