found these heads

They also sell some rocker arms (they are designed for push rod oiling)

Custom comp cams grind for 560-580 lift (with 1.6 ratio arms) and 210-220 duration at 0.050 thou.

I was planning on running a LA intake, so the bolt pattern doesn't worry me. I not a big fan of the stock dodge pcm program.

Just throwing out what I'm thinking.

One of the problems with that intake, is the thermostat is mounted where the old style LA mounts, more centered
Its in the way of your ac compressor.
Compare the intake,(and several companys offer that china intake under different names, ie crosswinds etc. ) to a edelbrock 7577. It is a magnum intake replacement to convert to a carb. Notice how it offsets the thermostat to clear your compressor.
I am going to pm you a link to a site to read up on.... I have learned a lot from it.

One other thing, I believe stock magnum heads flow around 190cfm..... With a 210-220 duration cam, headers, tune etc. IMO you will probably be 300hp or less.... at the rear wheels

That is easy to bypass with a relay...... and a pressure regulator.

 

Not saying it's hard to bypass I just think it's pointless. You gain more with fuel injection than a carb swap

Powerwise they are about the same, WOT. FWIW , Mike never said, but I suspect he is staying Fuel injected, just something other then mopar.

Personally, I just ordered a 7577 manifold to convert the 2000 5.9 I am putting in my 87 dakota. The truck is already carbed from the factory. (3.9) Latter, I may put a holley sniper or something like it, but for now, its going to be a holley 670.

 

To a degree if you want driveability and good fuel economy it's fuel injected for the win. Also fuel injection can handle more power but that is usually way up there that no one who wants to drive on the street will need.

 

Those heads are magnum heads, La intakes will not bolt up. You can get these heads in either magnum or LA style. If you decide to go LA the options are endless(for intakes). You could even put on a 6 pack set up on it if you wanted. Of course back then they used the V twin compressors and some intakes didn't have provisions for a compressor. There are places that make brackets for modern compressors on the LA intakes. Here is a link you may find helpful...

Wow very cool info everyone, I was leaning towards a stand alone FI system, prefer a injector in the manifold style (EV6 LS9) injector. There are a few options to go, I want a 3 bar or 5 bar map sensor, but you can very easily run a carb for now till funds allow. I drove carb vehicles for decades, and I'm not afraid of them. I live up in the north where they have real winters and this truck will be used year round. There is no emission testing up here, either so you can do what ever you want.

I bought my 2001 1500 5.2L with a broken motor, and my son and I installed a wrecker special 5.2L engine. I've gotten 30000miles out of a $500 engine. My kid uses the truck for winter and school bottle runs and to visit his rural friends (aka gravel roads). I installed a LS 6.0L into my 85 corvette a few years ago, so I may also consider the LS route

I could just go buy a new truck, but I'm not a fan of monthly payments (and nothing these days get me excited to own). I drive new trucks for work and they end up in the service shop quite often.

 

I like to keep things brand specific so I would never swap an LS into a Mopar and I took on swapping a Hemi in a 2nd gen. LS motors are overused and I don't like them. Which ever way you go I'll be following the build

 

LS motors have the advantage of being easily available, for dirt cheap, and have HUGE aftermarket support. Putting one into an 97 or older truck would be trivial, putting one in a 98 or newer truck is going to be more complicated.... but still, eminently doable.

I agree.....
I believe one may have to consider using different guages and elimination of accessory stuff tied to the computer.
FWIW there used to be a site called lstak.com. He built a dakota and a durango with LS motors. Very interesting site. I think he is still on facebook, but im not a member, so not sure.
Brian was his name, and he sold motor mounts etc.
