Good for what? A block is a block, especially once you get into the Magnum stuff like what youre talking about

there may have been some minor changes from the OBD-I to the OBD-II model years, but yes, in the same year, a 5.9 out of a Dakota R/T is the same exact motor as a 4x4 Jeep as a 3500 Ram pick-up.
same block, crank, rods, pistons, cam, intake, heads, etc. you will see that some vehicles have higher Hp ratings, but that's because of muffler changes, such as on the Dakota R/T that was listed at 5 hp more than other equivilent vehicles.
the stock long block is good for about 400 crank hp with just a cam, intake, and exhaust change.

A lot of confusion over the R/Ts... When the R/T came out it got a better cam, in 2000 all 5.9s got the same cam, I have measured a bunch of them and have found that 100% accurate so both the people who say the R/T got the same cam and people who say they got different cams are correct. 318 heads seem to hold up a lot better than 5.9 heads, could be better QC at the factory they were made in or it could be that the 5.9 got death flashes that allowed the burning exhaust to burn the seats and valves or the lower compression doing the same thing. 92 and 93 magnums had the best ex. manifolds. Somewhere in the early 2000s they all got a much better Y pipe.

Really...??? I know they're very underrated, but that much?
How much cam are we talking to make that? (I'm assuming an RPM intake/proper carb and full longtubes/GOOD exhaust).
I am THIS close to selling my big block parts for the Challenger and looking for a drop-in 318 or 360 Magnum.

whatever the cam specs were in the 380hp crate motors... Mopar muscle put the 380 crate on the dyno and made like 408 crank hp. I'm thinking it was up around 230° @ .050, 110 LSA? maybe someone else can say exactly what the specs were on those crate motors. the heads as cast flow in the 200 CFM range, which is good for 400 hp if you get a cam that uses all that CFM. but, like I said, the stock intake isn't going to be making 400 hp, because it's all used up by 3800 rpm.

I agree with the big guy. Heck, a 360 will do 400 hp with cam, intake and exhaust swap, and the 5.9 has much better combustion chambers and exhaust flow.
R.
So you are saying that the low compression, 50,000 mile 1974 360 truck engine I have, could turn into a little beast with the right cam, the air gap eddy intake, and the cnc ported eddy heads (61 cc chambers, 292 cfm at .600 intake, 211.5 cfm exhaust), and good headers. I was considering the '70-71 highfow exhaust manifolds with electric cutouts. Or a small turbo for those times when you want just a little more.
Too many cars, too many parts, too little coin, too little space to work in, too little time left to make it all happen!
Update: down to one ride, still too many parts, a little more jingle in the pocket, gaining space, and it's going to happen this year!

I agree 100%.
A local guy bought a 380 crate engine for his Cuda and using the recommended parts, a 750 Holley and headers- the engine tipped the dyno at 417hp

228/232 .501/.513 Don't remember LSA. I think this cam can support more HP than your typical stock magnum heads can flow so upgrading heads later would not necessarily mean upgrading the cam. I believe it was used on some of the higher HP bigger inch crate engines as well. I am happy with it in my junk!

I see Hughes has a new Whiplash cam for the 360 Magnum. Duration is in the 220's i think, lift over .500". That should about qualify, yes? Spendy though... $400. Compared to their other Magnum sticks anyways.
360 Magnum, RPM Air-Gap, Holley DP, Whiplash cam, long tube headers, 2.5" mandrel exhaust, stick, 3100lb car... Hmmmmm... . . .
