    I'm a retired Master Engine Machinist and I've assembled hundreds if not thousands of engines and let me just say that it was a nice thing to see that you used the speed wrench and not any air tools when assembling the engine. Someone who knows does NOT use air tools when assembling engines. The speed wrench is your friend. You have to be able to feel everything when turning bolts/nuts.

      the piston was torched, not broken from ring butting. granted there are some solid imprints, but the piston melted first. after the loss of compression of a ring butting the aluminum is not going to pile up flakes like that. the fuel was not adequate for the cylinder pressure of 11% overdrive and 10:1 compression.

      Aluminum heat treat the opposite of steel. When you heat up to 600, 700 degrees and up and then quickly cool, it anneals. The nitrous runs with helium quenching does it. Add ring gap and a few other problems and it all ads up.

    That was 100% ring gap's fault. I would like to have seen the piston out of the cylinder with an up-close inspection. Plus, those pistons didnt look "great", they looked used. My guess is the ring was not checked or gapped properly for this setup and/or was damaged on a previous run and this was the straw that broke the camel's back. Makes for some good youtube though!

      40 years ago, it took me 5 four hour nights to get the rings gapped on a 396 build I did.
      Every piston checked. Every ring gapped until exact spec by sealed power attained.
      Every valve spring height, every guide, every pushrod length. Every rocker contact tip. Main and rods. Cam and crank endplay.
      Deck height. And repeatable cc of each port and chamber. 60 man hours on one engine.
      Now I have a life. So, no time to build anymore of these types of money pits.

    Fellows - I used to have to make slush baths at different temperatures for conducting radiation studues on hydrocarbons. So we need a selection of organic solvents to satisfy our need for a variety of slush temperatures. I froze them all down with liquid nitrogen. I had some very nice thermocouples potted in silicone rubber for confirming the slush temperatures. But CYCLOHEXANE just ate off all the silicone every time. The only one of my solvents to do it. Later I found it was excellent for taking the glue residue off sidewindow glass from those stick-on plastic frost preventers for car and truck and huge rig operations in the Prairie Provinces where she goes down to minus 60 degrees in December and January. Cyclohexane will eat that stuff right off the glass licketty split. Keep a bottle around your shop. It is highly flammable, however, and evaporates really quickly. Store it in a fairly tight-fitting cardboard box inside a metal storage locker. No smoking when using it. I hope that helps.

    Having owned a 383 in a 71 jimmy, my opinion is its a high torque motor not designed to be revved out, broke engine mounts then distributor would hit firewall on old gmc firewall.
    Mine was carbed mated to old 3 spd 373 gears 4 inch lift 33 mudders, wolverine cam.
    Still not a wind up motor and good for 420 hp 440 tq.

    Fire ring expanded because of the heat , cracked the piston, aluminium powder burnt/melted/vaporized being small particles,the bigger parts bounced around.
    Cylinder was running lean,it's way less colored by soot than the two others : 12.4 AFR for a boosted engine is not safe AFR as i know.
    Ring gap was incorrect + lean cylinder = kaboom.
    12.4 AFR on ONE wideband is just an average ,so you definitely will have at least one cylinder leaner than that.
    You should try to check AFR per cylinder just for fun on this same set up,could be interesting to watch,and a safe investment for your builds.

      @@stanleykendziorski7964 a few things to mention here from someone who has grown up building engines, it's the family trade. They said they had sprayed the piss out of this engine, it is well known that nitrous cleans carbon deposits, especially loose carbon, the engine has *almost* exclusively been used for dyno purposes, typically engines don't build and hold onto carbon as much during high intensity/rev short duration running. Duration is exponential to carbon buildup where as intensity is linear. And the third, they only used 93 with octane booster or legitimate race fuel in this engine. Most pump gas has the same additives so the octane rating doesn't matter to much for buildup, however octane booster especially the expensive brands have considerably better cleaning agents than pump gas. Race fuel is usually even better.
      I'm not saying you are wrong as I have never sat and put the same engine on the dyno hundreds of times but it is believable, and not outside the realm of possibility.
      Same way as how some claim it was ring gap that took a chunk out of the piston. When metal overheats it becomes softer and as soon as it melts even a little bit it can do two things: melt to the wall, or harden enough between strokes to chunk out like it did. But they never removed the piston to see if it properly melted. Though I doubt it was ring gap as they sprayed the piss out of the engine, and without the rings gaped for the spray it would have turned into a frag grenade.

    I don't know about you, but I see lots of melted/eroded piston all over the inboard side of that piston crown. The area where the upper land "blows out" can sometimes indicate a cause. When you see a piston land blown out on the edge near the intake valve, it is a classic sign of detonation. Similarly a hole in the middle of a piston is likely preignition. Too small a ring gap cause a break out anywhere along the circumference. That piston was likely toast before that blower was installed as they talked about. Someone was overly optimistic on the nitrous use and remodeled a piston on the fly.

    • @ferrumignis
      @ferrumignis 3 ปีที่แล้ว

      Detonation is certainly a possibility though it's hard to tell from the video, even though they do a decent close up. The big gouges are obviously from the chunk of piston that broke out, but what looks like detonation pitting around the edges could be carbon deposits. Shame they didn't show a close up of the bore to see if the typical vertical marking caused by ring butting was present.

    It was a pitty that they did not strip it and measure ring gaps for each cylinder. Then at least for the next build we would know a good clearance to stay above. Also give some idea of whether clearances piston ring manufacturers supply are where we should be. If there was plenty of ring gap then you could argue that the top ring needs to be lower in the bore for a thicker top section.

One day I pulled the heads to replace them and there was a chunk missing off a piston very similar tho that just not quite as big but I could see part of the ring. I went to the local carquest asked if they could order one and they had a .030 one on the shelf for $15! I had it pressed on I think I may have swapped the rings over to the new piston and whahlah perfect. It was from temporarily using 67cc 305 heads I had tossed on to get it running and I was being cheap and ran 87 in it now n then... The compression ratio must have been 10:1 ish and yeah 87 not a good combo, but I was a kid and was broke all the time and it bit me.
