by any chance dose any one know the stock cam specs for all the gas engines? I would think that the 3.9 and 5.2 would be the same and the 5.9 would have its own and the v10 would have its own.

 

Don't know about the V6 or 10 but they claim the 5.2 has a bit more lift. I have cams out of a 318 and the 360 and they look identical. I didn't mike them so it may be true. Here are the specs i found...
318
Specification Intake Exhaust
.050" Duration 184 193
Cam Lift .258" .269"
Valve Lift .387" .403"
Lobe Separation Angle 109 115

360......
Specification Intake Exhaust
.050" Duration 205 196
Cam Lift .265" .265"
Valve Lift .398" .397"
Lobe Separation Angle 113 117

 

thanks I have also herd the claim that the 318 has more lift I read some thing that said the cam specs changed a bit from year to year for emissions reasons do not know if this is true or not I just found this the 2 on the far right are interesting to me and I thought they were fake cause many people say that the r/t cam was not real https://www.ramforumz.com/attachment...pecs-jpg.9927/

 

The 5.2 had more lift but the 5.9 had more duration so they probably perform about the same.

 

I think you are on to some ting there I am in the planing stage of build right now and am trying to figure out what all I want to do. one of those r/t cams would be nice but if I want one of them I will have to get custom ground most likely cause I do not think I could get one any other way. another thing I thought of was if I ever find out the cam specs for the v10 is having a v8 cam ground on them. do you think a custom ground cam with the 5.2s lift and the 5.9s duration would be a good idea or a bad idea

 

Custom grinds are not inexpensive..... I would be more inclined to be looking for an 'off the shelf' cam that made power in the RPM range where I want it.

 

the goal is a wide power band that is fun and engaging to drive may get a bit spirited from time to time off-idle to around give or take 4700 rpm I have no need to spin to the moon it dose not need to sound like a race engine but a bit tone that says I am not sock would be welcome

 

do any of these fit my goal https://www.summitracing.com/search/...rder=Ascending

 

I kinda like this one... Likely a smooth idle, and gobs of low end torque, which, in a truck, is what you want. That, and since the stock kegger manifold runs out of breath around 4500 RPM or so.... no real point in having a power band much above that.

 

that one seem good what do you think of this one it is very one you linked says may require computer modifications that I can not do on obd1 and requires spring upgrade this one says requires spring upgrade only can I run 1.7 rockers with it https://www.summitracing.com/parts/c...8-9/make/dodge
