Camshaft specs

[Johnmopar1954]

Hi. New member here. Does anyone have camshaft specs for 1999 Dodge Ram 2500 V-10? I'm building my new engine for a twin turbo setup so I need to know lift, duration, etc. to see if I can have my cam ground for turbo specs.

I would honestly recommend just degreeing it so you know for sure

Which would be after him getting his reground. Likely why he was asking.

Op, wouldn't make more sense to buy a viper grind or an srt10 truck grind? Instead of regrinding your and removing the surface hardness?

How do you figure ? Gotta tear it down to pull the factory cam in the first place, very little work to pull the heads and set the equipment up and go from there. Then you have a for sure answer on what exactly you have and can move to something else from there. Rather than guessing with an internet spec sheet that is a crap shoot as to tyke accuracy

My apologies. I did not see what you were getting at. Yes absolutely he could plot the lift points etc to get the idea of what he really has.

No worries. If it were one of the v8s i could post up specs and everything. The issue i see here is the v10s are pretty highly undocumented in these fields. The v8s are pretty widely documented themselves and there's a lot of bad info out there on them ranging from factory valve sizes and head differences, cam specs, and anything in between. I just think it's better to know for sure than to trust spotty documentation lol

Ohhhhhh for sure. Cams are black magic in the diesel world still as well. Is about a joke.
