Lol. I just came on here to post this video. Saw it on Facebook

If it has tits, it's a liabilititty.
What's up with the gay club music intro.
Lost me already!
I have the actual magazine that article is from. It's kinda washy. Theyre usually selling you something. For me...I'd like to see more of what people are doing with their magnum valve train , stock , to make it work. Sure you can use really expensive behive springs...but you can also cut the pockets and use regular **** too that's under a certain o.d The hyd roller doesn't really need a lot of spring for all the armor that's put into valve train.
People get the heads from some builder or supplier with valve n springs let's say.. and then still spend a $hit ton more for studs, guide plates, rockers, adjusters..
Stuff like that was always kept secret in the LA vs Mag head debates. Not to veer off too much.. but fact of the matter was/is the LA was/is always cheaper. It's the hype of 1.6 and closed chambers that most became blindly lusted after. Imo
Anyways..the spring pockets aren't deep, you have to stick a longer valve in them imo to open spring choices aka cam choices up..and keep it affordable.
90 dollar springs vs 200+
Magnum valves probably cost more than a stainless 11/32 5.011-5.025 as well.
The rockers.. aren't they fine to about .600?
Isn't it that people don't raise the rockers and create binding issues? How much is all the stud mount guide plate conversion $hit, like $650-$800? Plu$ pu$hrod$ Meanwhile the LA gear is 300-500? on average. I'm doing some on my truck and raising the rockers to compensate the longer valve then see where I'm at with preload. I'm not trying to spend near what guys buying done heads and then all that gear for stud ****.. again, on iron small port heads. Always left out of the discussion when debating of course. Hard left now going hard right back on track..
I'm not impressed with the outcome or his taste in music... in fact.. like his piston reversal..he probably reverses his boxer shorts so the hole is in the back

To me the way I’ve seen it Magnum have the advantage as a stock long block where you just add cam intake and headers but when it comes to full build especially when comes porting LA is the way to go.

That magnum needs EQ heads, 10:1 pistons and a good cam intake combo and it will make 475hp and 600hp on spray
I actually prefer these mild low dollar builds it's fairly well documented how to make 400-500+ hp, I imagine once he adds 4bbl could see 10-20 hp gain would be enough power for a good percentage of the guys out there, I looking forward when he gets around to the 5.2l.
Very good thread at speed-talk.com about the 380hp crate motor and some mopar performance cams. One guy on that thread was in on developing the 380hp motor and worked for chrysler so very Informative. Seems the 380 cam had .529/.543 lift with 1.6 rockers and the published specs are for 1.5 rockers. Also states that the 380hp was made with a 600cfm carb. And a 750 carb added 20 hp

Mopar should have sold only one crate 360 and used that cam, instead of one with no cam and one with too much cam.
The one Richard used is not far off the one I used in my mild 360 magnum build:

@273 It’s good to see some mild cam stuff for the guys looking for a true easy going driver. I’d go to car shows and tell those car club guys asking what’s in it that the 5.9 has zero deck slugs and a Hyd roller at 224 intake with the then Edelbrock heads and tti headers. They all said I’d be lucky to make 350/360 hp.
Yeaaaaaa, OK! Thanks! (Not!)
@67autocross , I like your cams lift C-line better. Works great with Hwy gears. Who’s cam is it?

Wish it didn’t have crap in the way of reading the good parts.
Cracks don’t mean anything not in the water jacket. No different than 3% leak down from ringsLol I can't wait until he pulls the heads and finds out they are cracked

If you look at my dyno sheet it’s crazy what kind of power you can make with a stock magnum with a small cam and well ported heads….
