Default Stock cam timing specs.

I'm trying to use an online calculator that is asking for exhaust lobe timing. Anyone know this?

Tried searching. The word "cam" was removed from my search. Please Dodge forum administration gods hear my pleas for a search engine overhaul. This site is almost perfect. I'm thinking words like "cam" should not be discarded in searches here.

Like others have said, search with more letters like Camshaft or use "Quotations" for exclusive searches. The letters were not removed, just way to generic.

Aha! quotes is the secret weapon I see. I love the search feature but am still learning to make it sing.

Good tip, thanks!

LOL! Awesome master tech! I needed it for my 1995 even though I forgot to mention that. The older 2nd gens have slightly differnt cam and thus cam timing than the newer ones apparently. I was originally trying to find the exhaust lobe center in order play around with this calculator. With aim4squirrelss link I was able to calculate that it will be at 109 degrees BTDC on my year. That link has the cam timing data for the old 2nd gens and the new ones too.

Thanks again everybody!
