Thank you Steve for all your videos and interesting content. I showed this to my 89 year old dad. An old blacksmith mechanic and tried to explain the tours with this engine and what you gone through with it. All the money spent on cams and his responce. "In the old days, when things went off side with parts and costs we saved the old parts and built other engines around the part that didnt work with the one from start. We saved money in that" Even if my dad is old and somewhat a bit off in memories as soon as he see videos like this, he comes around lie an old B18 volvo engine that refuses to quit it´s lifetime 🤣🤣🤣 He still teaches me at age 57 how you can turn around a failure to a victory by just think outside the box.

[@keenanmatthews1208]

11:30 I build electric motors as a job. If you're trying to test ohms on the wires or checking grounding conductivity you really need a micro ohm meter to do so with any accuracy. Most DMM's will just say .1-.2 ohms and people interpret this as the same reading and call it good. If you're checking the insulation of a plug wire you should unhook from the motor and test with hipot and megger.

[@dennisford2000]

As well as scope of current and voltage. On coils/injectors induction

[@JohnClutch1]

When your camshaft has nearly 1" of lift and the powerband lays over at 6500 like a dump truck motor, you got some cubic inch to deal with 😮

[@Killah68]

Is that throttle body kinda small thats a big compressor trying to get some serious air.

[@TheTherealdarkhorse]

Talk to Sonny's Engines. They are the 1,000 plus cubes masters. That throttle body looks very small for that cubic inch. Lobe separation is enormous

[@roadrunner4404]

Boost will help that. I agree. Airflow?

[@kasuraga]

The way it lays over does make me think it's being choked somewhere

[@mi16pim]

[@dennisford2000]

First thing I thought when he said 120 degrees.

[@TheTherealdarkhorse]

@dennisford2000 129 degrees I think is what he said. There goes all your high end hp and torque. Cam #5 ? 108 to 114 I would say ok. Boosted doesn't need huge overlap. 114 is great for low to mid rpm torque. 128 is obnoxious I would think. Why would boosted need that much overlap. The charge is forced in. I dunno. 🤷

Someone actually said not to think anymore? Has that worked for them.. LoL , you keep doing what you want, it's a good formula.

[@jryer1]

Sonny's 802ci monster motor, pump gas compression (Motor Trend article). Specs below. Hope it helps 70mm custom grind Lift - 600 intake/580 exhaust (theoretical lift at valve 1.110) Duration - 284-degree intake, 314-degree exhaust at 0.050 89-octane dyno produced 1,417 peak horsepower at 7,100 rpm and 1,140 lb-ft at 5,800. Of course the specs on that engine are probably different than what you're dealing with, but the comparision may still have value. Good luck

[@WildEngineering]

that probably had a proper intake manifold on it for NA. Steves intake is less than ideal for this many cubes N/A

[@willemvsp7544]

Hi what is lsa on that cam

[@jasonfikes9514]

In my limited understanding, that is a lot of cam for the compression. But that doesn't mean it's the wrong cam. When the boost gets added,that engine will become an entirely different animal. So enjoy hearing the thought process. Great video as always. ✌️😁

[@approachingtarget.4503]

The dip in the mid range on #4 is directly related to the exhaust system. Number 5,7,8 is because air is being robbed from adjacent ports. Alos the furthest away from the throttle.

[@dinosshed]

I was going to suggest running it without the headers just to rule that out. A set of zoomie pipes would have been better. Chances are, it'll all clean up with boost.

[@Cronus_1]

Yup. Lack of proper scavenging from the exhaust.

[@Racinls1]

I was thinking same thing if the cylinders were still being starved of air. But I'm no expert Those are huge intake ports sucking through that throttle body Could static pressure of downstoke ever not be enough to pull through throttle body?

[@airtightindustries]

I absolutely think Steve is up against the exhaust system. It looks like it's been designed for maximum restriction with four of the cylinders having an extra 90 degrees of performance robing bends

[@danmyers9372]

@@dinosshed- You can’t run zoomies on an engine dyno. At least not without fabing up a custom collector box for each bank to catch the exhaust and then route it back to the dyno room exhaust.

I finished watching Todays Video Steve where You switched to the Smart Coils. The Monster 903 ci Hemi wants a Super Long Duration Spark that a Vertex OAX External coil Magneto Delivers or Modern MSD 12 amp or Top Fuel 44 amp. Original Vertex Magneto delivers a spark duration of 40 crankshaft degrees. MSD CD Capacitor Discharge delivers spark duration of 20 degrees Typically. Going way back You will recall the MSD 10 AL CD ignition Box large Aluminum Gold Anodized body that simulated a Magneto. I think MSD needs to build a Custom Ignition coils CD system for You. Too bad no way to install a MSD 44 Amp Magneto now. Might be possible but thats up to You if course.

I forgot one other thing often I’ve seen engines rollover on top end solely as a function of lack of ignition timing on pump gas. Of course, this may not be the case with this. I do think that camshaft timing could be the reason for the top end dropping off so much .

[@blanchae]

Exactly what I was thinking, camshaft timing. Could it be valve float?

[@stevenbelue5496]

Maybe retard it and see if it moves it up?

[@stevenbelue5496]

I assume he's tried retarding it to see if it moved up? Maybe it still needs more duration, just thinking back to the days when that 283 had a cam that sounded so radical then the same profile cam in the 454 sounded stock.

Would dual spark plugs help? With the huge bore at higher rpm, would the flame front propigation be too slow? Random thought I had.

[@starionslider2116]

Funny how people say they dont want to see you think…..but seeing people analyze and compute problems is one of the coolest processes to watch. I remember my high school auto shop teacher was super smart guy that taught me (probably not even on purpose) how to run through a instant flowchart in the brain to find a problem. I could watch him think and talk his way around problems with cars and talk out loud during the process and usually would figure it out or be in the right direction pretty quickly. He will always be a allstar in my book because of that.

Clearly, you know your shit pretty damn well, and you have a likable KZbin personality. The dyno runs and numbers are cool, but how you arrive at them, establishing a base, and your thoughts while working all the bugs out is super cool.

[@TD2821]

I called it. If you review my answer on the previous cam video regarding this engine, I suggested a .600" lobe, 285 / 310 @ .050 on a 122.

[@miceinoz1181]

It is the thinking process you record that makes all the difference. When people want to query the hours they get billed for, they are paying for your live thinking when correcting a problem. This not only applies at SME, but all engine build dyno sessions everywhere. Yes, some engines fall right in at fireup, but when you are doing something out of the box, this is not the case. Very educational to all. I would do the coil swap first (easiest), then if needed, the injectors. For your question, I cannot see the relevence as this engine is being built for a supercharger, so the NA cam to compression issue will probably not translate that well. Stick the blower on it and see how it runs. Pushing air into it may change everything.

[@marynunn1708]

I think you are on target. A lot of fuel and air and no pressure to use it. Thanks Steve for all you do for us.

[@Stormin06096]

Great information. What a great lesson on how the spark is delivered to the cylinder. Sounds like the MSD 600 is delivering a large amount of energy in the beginning of the combustion event but it is incapable of keeping up with the demand as the flame front moves away from the spark plug especially at the higher load conditions. I wonder if this big cylinder needs to have two ignition systems.

[@Turbostang500]

Love hearing you go through the thoughts. That is troubleshooting at its finest. More people need to follwlow along with you to get an understanding of what troubleshooting is about. So, just curious, do you think the large overlap, low engine rpm, and short runner is creating a reversion that is getting into other cylinders? You might not even see this comment given there is about 900 on your video. No problem if not.

[@Turbostang500]

Well, commented too early. Glad to see the ignition wasn't up to the challenge. It really would have had issues with a little boost. I don't know shit about engines like you do, but it does seem like the cam overlap would really drop dynamic compression a bunch. Again, I don't know shit. Would a longer runner help with any of this?

Couldn’t agree more with others… Seeing you work through the problem is often as insightful as the answer itself! Keep it up!

[@mikehunt8968]

My first thought was a gas flow problem at the back of the plenum chamber, where it slopes down ... reversion pulses interfering with the incoming air... NA is always more picky with intake geometry and resonance... If that is it, you could try an experiment by making a spacer for the inlet manifold top, to raise it up, maybe 1/2 inch, and see if things change....

The fact that all 4 cams seemed to fall off at the same rpm would indicate valve float to me. I wouldn't have thought a cam grinder would have made an error like this, but they did screw up 2 cams.
