There is/was one other Hemi in the area. It was a stocker and it blew a few weeks ago. No claimer rules here. This engine has upgrades throughout.

It is a modified. They have raced for about 15 years locally. This is a complete new car. They are still running their old car and motor combination. I had hoped to have the engine done to start this season, but those plans went away due to parts availability and such.
Their current engine is an R3 410" W-2 set-up. Hoping to see more power and lighter front weight percentages.

The sanctioning body is AMRA. As of now, no GM LS engines being ran. It is just a matter of time though, I believe. Steel blocks are mandatory.

GM parts was experimenting with an LS motor at our track a couple years ago. For a possible higher HP level ZZ4 type crate motor deal.

There is few guys that run the 525 crate LS motor in mods around here. In fact one guy won a few USMTS races and people started crying about the lighter weight. They made him add weight at the mid plate and he still won. He finally put a mod spec motor in and won with that too. After that people quit crying.

When we switched to ZZ4 crates years ago same thing happened with us. We were the first to run them. They added weight, we won. Some other racers switched over. But we still won. Then other racers whined that our motor was "special".
So one night after we won, a guy says "I want THAT motor" So we said ok, buy us a new one and you can have THAT one right NOW. So we yanked the motor right after tech and handed it too him.
Soon all the cars coverted to crate motors and were paying $10K less for motors, turned less RPM, and lasted much longer.

It has a Bert transmission/bellhousing/starter set-up. Also, a belt driven pump on the rear of the engine for the engine oil, fuel system, and power steering. The engine oil system is not a dry sump. The oil is still stored in a custom built pan with an external pick-up line. The flywheel was the hardest part of the arrangement. I worked with Bert to get the bolt pattern correct. The bellhousing is the same on the Hemi as an LA motor. After Bert did their best to get the crank bolt pattern as close as they could, I still had to modify it to get it to align properly. I ended up sending them a stock flex-plate. Hopefully, the next builder won't have any problems getting their flywheel right the first time they order.

I regret in posting this,,but I know some of you are interested in this project. After getting the bugs out of the fuel system, the testing progressed well and it was time for some 'real' laps. The third afternoon of tests ended in disaster. #3 rod decided to go elsewhere...I am not sure just what happened yet. I will do an autopsy when I get the motor in the shop. It appears, by looking in the hole, that a rod bolt broke and let the cap come up on one side and,,,it went down hill from there. 
The motor had about 3 hours running time on it and was making some serious power. 40-50 hot laps and we were all excited with the performance.

At this time, I am leaning toward a broken rod bolt. One bolt is a clean break, while the other one appears to have bent/broke. Also, enter into this mess, a blackened crank, that points to oil starvation. I am speculating that one bolt broke, allowed cap to start coming off and going out of round, which caused the excessive heat/blackening, the cap came clear off, piston stayed at top of cylinder and crank pin broke beam off..what ever happened, happened fast(7000+rpm) and the damage was severe. The other rods and bearings look good.
I say 'good', in as good as could be expected with all the trash floating around in the oil and crankcase.

ARP #8740 bolts were used as that is the bolt supplied with them.
Probably should have upgraded, but have used them without any problems in the past. I am still at a loss, as are others apparently, just where the oiling problem is. I would have to guess right now, that it is in the crankshaft. I KNOW all oil passages in block and crank were clean and clear upon assembly. All clearances were acceptable to my standards with previous motors. The 'previous motors' do NOT include a Gen 3 Hemi though. I can't imagine the clearances being hugely different on a Hemi versus a big or small block Chevy, small block Mopar, big block Mopar, etc. The blackened crank is what really makes me wonder just what is taking place in these motors at 7000+rpm.

it sure seems to me that the only time I hear of a rod leaving a new hemi is when it has a drag pack intake. there maybe other cases but I dont know of any and there are new challengers and chargers running low nines with boost at 4000lbs not having this problem

Correct there is a oil problem running a stock crank at high rpms' i forgot which journal or journals, but it was one of the middle rod bearings would lose oil at high rpms.
The fix is an aftermarket crank that drill the middle rod journals differently to help the oil flow.

First off sorry to see it. Not being a new Hemi expert, But. I question the broken bolt being the cause. How did the journal that hot after the bolt broke? I say lack of oil. At high RPM centrifugal force is trying to restrict oil going into the main journal. If the main doesn't get enough the rod is starved even worse. Just my 2 cents.

The ignition is the MSD Hemi6 setup. The timing was 'locked' at 19* with a laptop. I am putting my confidence in the ability of the young man that did this, as he was the one that installed the system and did the research/study of the system. I only know as much about the system as he explained to me, but I know he did not intentionally install any type of 'timing curve' into it. Are you still thinking 'detonation'..?

The mains look good. I am open to any/all theories. The mains seem to be fine as far as oiling goes, but, I'm thinking the oil is not getting out of the main and on into the rod oiling passage. The #3 rod was the only one that seems to have starved for oil. #4 rod had some damage, but I believe it was caused by #3's problems. It would appear that the #2 main maybe oiling the #2 rod more than it's oiling #3 rod. I am having a hard time understanding why the crossdrilled crank is not moving more oil. Just for some more info, the #2 and #4 mains are the only mains crossdrilled on this crank.

It is a wet sump with a Barnes crank/belt drive pump. 3 sections to the pump system..engine oil, power steering, and fuel. It let go midway on front stretch, right at flagman's stand. Was kind of an uneventful thing though, we were the only car there testing and nobody in the stands. I just heard a 'clank' and then all was quiet..

I only know as much about the system as he explained to me, but I know he did not intentionally install any type of 'timing curve' into it. Are you still thinking 'detonation'..?
The only way to know for sure is to hook up a timing light. Here's how you do it. Its crude, but it works.
Pull the #1 coil pack out. Insert spark plug wires into the boots and the other end to the plugs.
Bring the #1 up to TDC on the compression stroke.
Use a piece of wire and bolt it to the front cover and use whatever bends it takes to get it over the damper.
Use a piece of masking tape on the damper and mark TDC under the wire. I like using a dwell dial timing light for this application. Fire it up and turn the dial on the timing light while at idle and rpm. You'll then personally know whether the timing was locked or not.
Was there an A/F gauge in the car?

Just for some more info, the #2 and #4 mains are the only mains cross drilled on this crank.
From what little info that is out there about the oiling systems in these engines, The good aftermarket cranks are not cross drilled at all. I have to wonder if the cross drilling is the reason for many of the oiling related failures
The oiling system issues doesn't put me off building one of these engine, my fiance and the two unfinished engines I have do

Not quite a year yet,,but, I have this POS SOB almost back together and ready for another test. COMPLETE new short block other than cam/lifters. Molnar crank/rods and Ross pistons. I am getting too old for this stress, head aches, heart aches, etc.

Minor details
this go-around works out better for you New style motors + building more HP = sometimes s#*t happens

That has crossed my mind SEVERAL times in the past few months!! But, as a wise old(er) man once told me about motor building.."You are only as good as your last one." He was meaning, NOBODY remembers all the previous ones, just the one everybody is talking about at the present time. So, I HAVE to make this PITA a good one before I break camp.

Got to test this evening. Motor had been run at shop on gas till it used up 5 gallons. Switched over to alky for testing this evening. Put about 15 laps on it with 5200 RPM max. Checked everything over and started letting it eat alittle. Had rev limiter on 7000. Ran about 10 laps, checked everything over again. Track needed alittle watering, then put another 15 or so laps on it. All seems good right now. Driver was wanting to turn it up some more!! He was love'n it!! I will allow alitle more next run. It was picking the left front up at mid straight-away. Going to give it just a bit more fuel pressure...was a tad low at times. Hopefully, this thing is fixed with the new crank.

Sounds encouraging
Remind them that lapping the 2nd place car will lead to rule changes

Got the first race night on it. All went fine with the motor. LOTS of problems getting it hooked up. Burned up 2 new tires. All seems good with the motor,,,it's up to the chassis man and the driver now.

Remember, Karl Kinser had to detune Mark's Mopars because they made too much power. Much more than they were used to with the Chevy. Too much power is a good thing. Just get to work on those shocks, springs, and bars. The wheelman will figure it out.

"...work on shocks, springs, and bars." Second race night....broke pull bar, broke yoke off drive shaft, bent J-bar and hiems.
Must be starting to get hooked up.
Going to longer track this week. Maybe see some progress there. Wheelman likes the motor, just taking time to get it all worked out.

i read that the 5.7 block and bottom end are built for 1000 hp----the only production line engine to do so---mopar admits that the stock heads wont support it (1000 hp)but those are available-----one of my friends is running a dodge nascar motor in a tubular chassis covered with 49 jeep skin at a drag strip in douglas wyoming---he has been getting lots of attention with it...

Re: Gen 3 Hemi on dirt.. - 08/26/13 05:31 PM
A 6.1 block and crank, 1000hp is doable. A 5.7 block for sure, crank rods and pistons...not so much.
