  • these old stock block chevs can make huge power with loose rings on forged pistons rods and crank

    William KiĺlWilliam KiĺlVor Tag
  • you obviously ran the rings too tight and added way too much cylinder pressure/temperature

  • "At an AFR of 12.2-12.4 it wasn't lean at all." OH REALLY? I run 12.5psi at 11.5 AFR because I understand that all cylinders won't be the same. That one with the peppered plug sure wasn't 12.2! If you guys can't tune individual cylinders, then you MUST run it on the rich side to crutch the lean cylinders.

  • 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.

  • I would have installed pistons designed for blower pressure. Also they really should check the crank and rods for straightness...and replace the rod bolts.

  • That piston has been damaged because of too tight a ring gap, no mistaking that damage.

  • First the green motor is not suitable for that truck, it needs more torque down low and less rpms it needs to get its horsepower and torque at lower rpms.

  • never liked sharp corners on piston domes, should be chamfered. best to use flat top when possible.

  • I think the blower belts are slipping or vibrating just enough to throw a wrench in the over all proper timing of this engine and caused the engine to have a failure.

  • Broken piston not melted. Those looked like brand new pistons. I can't imagine putting in new pistons and not using new rings. Standard rings will break pistons if not properly gaped, for modified running conditions, such as boost or nitrous. In this case boost via super charger. Then again I can't imagine spending all that money on such a dinosaur engine. I say give that engine to Nick and get yourself a gen III or IV LS or better get a gen V LT.

  • 15:39 the visitor stops the Trickflow spokesman from continuing the demonstration and explanation . Bit of a bum deal PAL. Aside from that disappointment the way you guys spot the problem with the motor and the response time . Great work. It shows how onto it you are. It was getting a wicked cane-ing in my view. Sounds NaSTy too.I'm keen to see what comes in the next edition now

  • Who makes low compression pistons for a 408 LS

    Scott HScott HVor Monat
  • I did that too, lifted a ring land on my 1st LS1 with a Magnuson I kept going to a smaller pulley until i ran lean when the meth injector got clogged. Spark plug was broken, pulled the head and piston looked just like yours. we digested that broken part. And cracked the Cylinder sleeve. so ... When with Iron Block, Mahle Pistons, H-Beam Rods and Crane Valve parts. Went 525 HP over 140,000 miles when built right they will last. D

    Dennis MurpheyDennis MurpheyVor Monat
  • Ring gap and the blower belt tensioner installed wrong coged belt and smooth pulley don't mix. Look at the belt slap. u said the push rods went in the original location but when he lubed em he holds them all in one hand idk but looks like that would mix them up? Not that it matters. The ring gap is what got it in the end.

    Justin ForeJustin ForeVor Monat
  • The little engine that could just finally got tired and gave up. Everything has limitations and the pistons had enough heat to start failing.

  • I love all the detailed explanations. I want a sbc 327 crank in a .030" over 400 block high-rpm motor build up from you guys. Somewhere close to 10,000 rpm. If Bill Jenkins can do it with late 60's early 70's technology it can easily be done with today's high-performance parts. Sure you can make more HP with other combos, but a fast rapping high rpm sbc is hard to not like. All info can be found on the net.

  • I think specing a cam for bottom end power on a positive displacement engine is the wrong line of thinking for longevity. The blower is already going to really wake the bottom up. Eliminating overlap and moving the power down on top of that increases cylinder pressure at low rpm a lot. This multiples torque to unearthly amounts. This is great for fun but this is what breaks stuff. Contrary to popular belief, Making power with rpm is a more reliable plan.

  • Also while setting up this and tuning it any backfire can cause this on hypereutectic piston . I don't no why I see a lot of this with hypereutectic piston . I took one apart the guy put together and was there when it back fired and ran like crap. He brought it to my garage to take apart and it was broken just like this and was a fresh rebuild with just a carb on it. Also the ring was broken in 3 pieces but not a scratched on the cylinder. We put 8 forged pistons in it and it ran for over 10 years. And he beat on it but took care of it also.

    Arthur RodesilerArthur RodesilerVor Monat
  • I have seen this a lot on hypereutectic piston. Cast pistons are better than hypereutectic piston. Buy forged piston always. I dont know what kind of piston they used here. I can just bet it was cracked from using Nitrous from the last time they used it and was gonna happened anyway. This engine has been pounded to death before it got the blower.
