Finally someone building a motor I have
Awesome, I'm liking those cylinder heads, there's nothing like new and shiny parts.
The 360 and 318s are very underrated and for mopar guys we know what they can do and the rest of the world still pushes the 350 chevy. Great engines but the 360 is another animal. Truely a little known beast that easily beats the 350. Love these engines
It really comes down to the copyright of parts. A water pump for 318/360 is 3 times as much
Great to see you guys back on this project.
My project reminder from last year:
"This is a timely project. I have a 1995 Jeep Grand with a 5.2L that I purchased new for my wife; I've been saving it for my daughter's first ride; we are starting a resto-mod this winter. The engine has 225K on the clock but runs great; what I understand from your statement 5.2 and 5.9 are almost identical. I may need to freshen up the engine, or maybe not; would you consider highlighting the difference between the 5.2 and 5.9 as you go along. Odd as it seems, I also have a 97 dodge with a 5.9 outback the barn; I don't know what I want to do with it, but this may give me ideas. Thanks for sharing..."
Our Project has stalled but not stopped, I'm still planning the 5.9 swap, but this last year and a half have been a challenge for us; we/I am back up to speed (mostly), and I'm slowly getting my shop ready for Winter projects.
I'm definitely going to pull the 5.9 this winter and tear it down; with luck next winter, it will go into the Jeep.
Thanks again for the update and the parts list, looking forward to your next video.
Stay well...
90% of people driving around with these small block Magnum Motors have small cracks in their heads at the values. If the values seat like they are supposed to, then it doesn't even effect performance at all as a normal everyday driver.
finish it up!
I got a 73 challenger with a 440 stroked to 512 ci, I also have a 99 dodge 4x4 with a 360, I can't wait for that motor to blow up. Please finish this project!
5.9 cylinder heads cracking between the valves isn’t an issue. They will work just fine. Just an FYI. The crack doesn’t effect compression or water jacket at all.
Loving the series can't wait to see it finished. Learning a lot of new things about this motor.
I had been waiting for this video for a long ass time!!!! Can’t wait to see more!!
Good video! When’s the next update?
Soon I hope!!!!!!
Glad to see you have finally given your base a long over due update. The underlying reason for delay was legit. Hope you will be able to continue doing at least this but with less time between them. Year was a little bit long.. course ours are starting to drag too so we can't be too critical LOL
I'm frothing at the mouth and loosing sleep waiting to go get the remainder of the parts sitting across the boarder. I've resorted to tinkering on an LS motor... ya, it's gotten that bad!
Im planning to have my 5.9 magnum rebuild coz its knocking and i kinda want it like what yall doing with that 5.9 magnum and i hope my guy can do it lol
I’ve had 2 Rams at over 300k on them with stock magnum heads. Were the heads cracked...probably...but the truck don’t care! Lol
They don't crack into a cooling passage, so no point pulling the motor apart to repair them! If the motor's already apart, might as well replace them to ensure a good valve seal.
When's the next video.. thanks guys. Awesome 👌 👏
You guys are awesome, I don't have a place to even take on that task or the nolage , Very interesting I do have 98 dodge ram 5.9 Very high miles and we are replacing water pump and timing chain !!
Nolage?
LOL crack problems
I really like this build. That being said you are going to be a good 100 HP shy of 500 RWHP. Using the stock intake is a fools errand at this power level and with those heads, also your cam is way small for 408 CI.
Might be cracked but it won’t hurt anything
I’m excited about this one. I’ve noticed lately the magnum is finally getting some much deserved love. It’s unfortunate the LS and Hemi stole their thunder. You going to dyno this thing? I’m guessing it’s somewhere around 500hp?
Chassis dyno session with definitely happen. Watch for a new episode coming soon of the final breakdown of what we will be installing.
There are a few manifold manufacturers that provide manifolds drilled for LA and Magnum
👍💪
Huh I was looking at heads .. I'm curious about these trick flow ones .. another one I was looking at was hq I believe?
Love this but you guys got too much money and time 😂 hope to god my truck works when it’s finally put together.
Awesome video.. thanks for sharing, I'm helping my bro with his 5.9l.. first time messing with these magnums ..
Good luck with that extra foot😂😂💀
What kind of cylinder heads did you get
How was the oiling issue from the block to the heads addressed? I must have missed it. The Magnum oils through the pushrod tubes and the LA/shaft through holes in the block from the main gallery...holes that don't exist in the Magnum block.
You are 100% correct. the rocker arm we used from Harland Sharp are designed for this Magnum Block and Trick Flow Cylinder Head combination. Stock roller lifters and hollow pushrods from Comp were used as well.
Was I understanding correctly that the jog you made was for drilling the LA bolt pattern into heads made for the magnum? Or were they LA style heads drilled to Magnum intake bolt pattern?
I'm building a Magnum right now from an 01. Converting it to coil near plug on a holley terminator. Not sure if heads are in my budget so I'd like to re-use my factory heads which are still in good shape, but I do want to have the LA intake pattern.
The jig was designed to be used either way. we used it for drilling the Magnum pattern in the LA heads.
I see the exhaust ports are still really small
With the LA shaft style rockers, how are you oiling them?
Are you drilling open the oiling boss in the magnum block and using solid pushrods (like an LA)
Or is the magnum style of oiling through hollow pushrods sufficient for shaft style rockers?
Harland Sharp sells shaft rockers that using the magnum pushrod oiling system to lube everything. That's what's going into this motor. there is a passage through the rocker cup and into the shafts which lube the shaft bearings. T&D performance make a very nice set of shaft rocker with oil guides to direct oil the springs. TrickFlow said that splash oiling the springs with the Harland Sharpe unit would be just fine for this build.

Thank you for the info.
I am looking forward to this particular build.
👍
What part number cam did comp send you? Or is it a custom?
Custom Grind. Once the block gets back from machine shop purgatory, all that info will be revealed.
Those heads crack there all the time and never will get to water there. Anyone who thinks other wise and has a set of cracked heads and think they’re junk please send em my way
What is the plan is for the rockers and bottom end components?
With the LA style heads and magnum block, we went with a set of Harland Sharp shaft rockers designed for this. T&D machine make a bad ass set too, but were over our budget. The bottom end we will go into detail on once it's here, but a stroker kit from Eagle is waiting at the boarder.
The 1st video made a lot of sense and was very helpful. Now You keep talking about LA series even though this video is supposed to be about a magnum. You have said both that your new head Is a magnum head and an LA style head. In short you confused me even farther than I already was. I have a wrist pin issue I need to rebuild my truck which will be my 1st vehicle rebuild. I've done motorcycles even been to school for aviation maintenance. But you seem to keep contradicting yourself and I can't seem to follow you. But you seem to keep contradicting yourself and I can't seem to follow you Can explain better but why do you keep referencing and LA engine if we are only working on and concerned about Dodge magnum? Will that head work on my 2003 5.9 magnum? Or is it an la head like you Contradictorily said at around 7:08 min? Please advise.
The Magnum/LA intermeshing is confusing, no matter how you slice it. This head is designed to work PRIMARILY with the LA motor, but with additional aftermarket parts (the rocker shaft system) can work with Magnum blocks as well. IF you use a stock Magnum intake manifold, you need to redrill the heads to match the bolt pattern. if you are going with an aftermarket intake manifold with the LA style bolt pattern, no need to drill the heads. I hope that clears things up a bit.
Где купить такую ГБЦ?
What was the cost for your haul in their video?
I would have to go find the receipts I've hidden from my wife. Heads/rockers and injectors were from Summit, cam and valvetrain were from Comp directly.
Noooooo im over a year too late, don't scrap those heads it can be repaired, long as they're not used for high output performance.
Use 5.2 heads, bigger valves...... knock down the flash on the runners, nothing overboard, round off the guide ends, and deshroud the valves..... huge increase in flow without extensive porting...... that and a next stage cam, wakes em right up
Sorry how much you pay for cylinder engine heads?
Warning!!! Danger to Manifold
Can you please explain?
Fully suckd now you have to drill,tap weld, do more work just to modify everything.
