The LA-Phant Meets the Dyno | MOPAR LA Small Block Dynamometer Session
The LA-phant: Episode 21
The time has come to see if all of Pop's planning and hard work have paid off. Once a mild manner 340 LA small block, this 437 powered by 110 race fuel is put to the test. The LA-phant is a naturally aspirated 437 MOPAR LA small block stroker build with sights set on 700+ HP.
This build is based on the Chrysler/MOPAR 340 small block which were known for their larger cylinder bores (4.04 inches).

That's awesome!! Your hard work paid off nicely!! Those heads are letting the cubic inches you have reach a high RPM for horsepower!! The stroke and wedge engine design in general ensure plenty of torque!! My 416 (340 based, 4" crank) made 525+HP around 6000 but the peak was at 6200 although it would cleanly rev to 7200, the Edelbrock RPM heads were the limiting factor (flow CFM). I used a flat tappet Ultradyne camshaft, 259/263*@.050" with .590" lift, 110LSA, for street use. Was a beast 3000-6000 for sure!! Love the LA-PHANT 437"!!!
Thank you for watching. Pop is extremely satisfied with the results. He hasn't been that excited in a while.
Your build sounds quite solid. Those are some solid figures.
My 1970 440 6-pack with Eldebrock intake and iski camshaft & lifters with 2 inch headers ported stock heads with worked over carbs from the Carb shop made 580 HP 567LBS ft on just Sunoco 93.
Very impressive for the cubic inch & the fact Mopar, like Pontiac is limited on cylinder head. I'd be very happy with that & most pump gas SBC guys would be happy as well.
LA MoPars are always a pain to get headers that match the ports exactly. We are doing a ported J-head 360 for a '66 Valiant, and the early '60s A-bodies are a pain to find ANY long tubes for. We found some on Ebay with 1-5/8" primaries and 2-1/2" collectors , so I'm sawing the collectors off and putting 3" on, but the head ports are 1/8" bigger, so I had to make tapered adapter plates to ease the flow (funnel) into the smaller header tube. Hopefully worth the effort and won't leak!!
For sure. Keep us updated on your project.
GENTLEMEN.... UNBELIEVABLE. AMAZING RESULTS.... CONGRATULATIONS FOR THIS ACHIEVEMENT.... YOU ARE THE MIRACLE....
Thank you.
Awesome Build 👍 guys I appreciate all your Tips and video's keep up the great build 😎🤙👌
Thank you.
You'll be surprised what we're going to put it in. That announcement video will be streaming at the end of March.
Oh yeah. Nice and respectfully Work Sir. Thank you for posting this Mr.
No problem.
Thanks for watching.
Thanks for the good video series. Dyno pulls with open headers looses power and torque, using a 18-24 " collector at minimum pulls in as much as 50-70 FTLBS of torque. Watch the TH-cams where they dyno no collector, 4 inch, 8 inch and then add an addition 18 inches... Each time the torque and power climb up across all different people doing dyno pulls on difference engines and dyno machines. Chasing that 700 without a collector the appropriate size is hard work.
Thanks for watching and the feedback.
Yeah, I also think those headers were hindering our potential. When we get the motor into Project sLA-ten we'll be able to implement some things hidden in our "back pocket."
Very respectable numbers, you should be pleased with that.
Well done🙂
Thank you. Pop was real happy with the results and looks forward to solving some of the smaller things that came up. ;)
Great progress, but I can't wait to see 700+! You can build a pump gas 408 that produces those same numbers you guys got, so I know your has more in it!
Edit: not discrediting the build, just saying it *definitely* has more in it :)
Good call!
There's a lot more in there.
Thanks for watching 😀
It's getting there. Try some better 2" headers and advance the cam 2 degrees. If the advance in the distributor isn't locked out, lock it out and set the advance to 34 degrees btdc. Just some places more HP may be hiding.
I definitely think some better headers will help too. We did make some timing adjustments and locked out timing while we we're at Voss. Pop also opened some exhaust ports a little after the session. We'll get it figured out by the time it goes in the new project.
Thanks for watching and following the build.
Been following this build from day one. Six hundred and thirty eight horsepower with 591 pound feet of torque very respectable. I wonder how much oil was in the pan, less could have made a measurable difference with the bigger diameter tube headers. Didn't catch the size you tested with? I'm sure you guys are satisfied and congratulations on a good and informative build!
YES! Thank you. Pop is pleased. We also picked up a few "tips and tricks" along the way. He will be looking into the placement of that galley plug later this month.
Man, If I had that power in my '71 Duster 4 speed I wouldn't know how to act!
Lol. It would definitely require some changes to a street car. 😉
Great video👍👍
Thank you 👍
How about long term and have you done any inspections
Great question.
We looked after break-in. Before the dynamometer sessions. Everything was awesome.
Unfortunately, we do not have the engine in a vehicle at this time. Even then, it will not be a street car and will see be run quarter miles at a time.
Now do a 408 for street use, pump gas . A 360 is much more affordable than a 340
LOL. Maybe on a future build for a future project. Thanks for watching.
@@MicsMotorworx I’ve got a 416 and a 408 in my Darts, but run both on 93
Neat.
I like how they never mention the CR and octane they run
Wish we could cover everything everyone wanted. However, those topics were covered in earlier videos.
Thank you for watching and we hope something positive was taken from the video.
me i just take a stock 318 motor apart .A RP rod bolts good ported heads balance it file the rings . a big bottle fun all day cheap FUN
That's one direction to go in.
I'm curious about how the lifter bushings worked out .
No issues during the pulls.
Those heads are really choking that thing down.....The heads are maxed out on a 340-360 engine...
The heads, or headers?
Is is this voss related to kenny scott or mark voss
He is Ken Voss. His sons race in PDRA. He's pretty knowledgeable on flatheads.
Are you kidding? PCV not hooked up, no header collectors? What else did you miss?
Our target HP. I let Pop and Mr. Voss make the decisions. I just captured it on video.
Thanks for watching.
Just a "Dickweed" comment or two (3).
1. Those headers are worthless. You could have helped them SOME with a 3 inch Diameter 18 inch long collector extension.
2. The oil pan. A better one would be a nice baffeled 10 quart running 6 quarts to lower the windage splash. Then add a scraper and a power slot kickout. Canton or Kevko makes a good pan.
3. Lower the oil pressure a bit. Use a stock, not High Volume, Melling type pump with a Kevko direct oil pump cover and have more oil FLOW at less pressures.
Just a Dickweed, always was and always will be. Most times I do know my azz from my elbow.
There are many ways to get more power out of the LA-Phant.
Those are some good ideas.
Seems to be a little weak for the quality of parts
There are a few tricks up our sleeves to get more out of the LA-Phant.
Tractor Dyno. Could I afford one of your engine for Super late model circle track racing?
I appreciate the thought, but that's not the business we're in.
We're just a lowly TH-cam channel journalising our hobby.
@@MicsMotorworx all there is Chevy crates up here. They all say ford, dodge cost to much, they telling me this with a multi million dollar hauler with a rolling shop?
Well... usually, Chevrolet engines.and performance parts are pretty cheap. Comparatively speaking. There are plenty of options out there for the Mopar Maniacs out there.
Yes maybe u could give me parts list of stroker. Plus while in pits u can walk hauler to hauler get any part
A majority of the parts for our builds are in the descriptions. I start them in the first video of the series. The LA-phant started as a 340. Those blocks are harder to find. LA 318 and LA 360 blocks are more plentiful.
Let us know how it goes.
A real oil pan will pick up 20 plus hp
As opposed to a pan that doesn't hold oil? 😀
We have a few tricks up our sleeves to get a few more out of this.
Makes you wonder why all those mopar engineers were so completely stupid, adding all that iron to make a short stroke long rod big block 440. Maybe it was having to warranty it.
The requirement to run it on race fuel. ;)
This thing does not like pump gas. However, you're right. The engineers could have taken away that compression ratio a bit. Then there the gasket material, life time of the motor, etc.
The great thing about the LA MOPAR type heads was the air flow.
Thanks for watching. 😀
