If the LS-Z isn't a square port head they wont work as the square port heads intake rocker is offset where the cathedral port heads are straight like the exhaust rocker.
@@wheels808 why though? If it got him on the road why not, they were only stock rockers with uprated truncheons so if they were the right ones on the LS-Z it would probably work on a detuned setup?
Maaaan I feel so frustrated. I can't imagine how Brian must feel like. But at least we know when everything is dialed up and ready this will be a right on BEAST!! Keep your head up B you're gonna get there!!
500whp is going to party man, Brian's car is going from clutch kicking the whole track to be an absolute smoke show. Glad the damage wasn't worse! Isn't it funny how you try to protect it from needle bearings with the trunion upgrade then the rocker arm itself takes a shit lol, gotta fight ya every step of the way
Man it sucks seeing Brian react to the damage, but hey as far as parts go it could've been a lot worse, and even if it can't rip this weekend I'm sure you'd rather it break now in the shop then throw a rod on the track or something. you boys will get it sorted soon, keep up the work lads
There's not a speed shop or all your car connections that can get a set of rockers for the most common American motor? The shop that built B's motor should be able to hook you up with someone. That car is gonna be a BEAST. Good job 👍
Sucks Brian can't catch a break with his builds. His effort deserves a ripper and I know he'll get it on track soon. Sending good vibes up your way, hope you all can make it happen soon!
I ordered roller rockers, new ti retainer, and pushrod length checker, will be measuring with the new rockers and likely ordering a second set of pushrods.
Yeah if you use a cam that’s not a gm cam you should def check length. All GM cams should work with stock length and the stock LS7 style hydraulic lifters. But when u got Bigfoot’s schlong in there should prolly check lol, I’m loving watching this build cause mines very similar with my e36 but taking way longer!
exhaust port temperature sensors relay a signal to the ECU that will cut back the motor if they get to hot, thus preventing the valves from sticking in the guides from thermal expansion... calibrate them to the ratio of thermal rating of the valves in line with the application specific valve guide to stem clearance that coincides with the thermal expansion of the valve and valve guide. want to run it that hot you need to loosen up the valve guides a few thousandths of an inch.
Aaaahhhhh man brian!!! This suck on a fresh build right before the event, I'm sorry this happend! just stay positive, it will be even more dialed when it's fixed... can't a guy just catch a break
'Sometimes good things can fall apart. Sometimes good things fall together.' Everything happens for a reason, there's no learning without failure and this may have taught a previously unknown issue that could've hit at a much worse time than on the dyno in a shop. Glad to know everything will be fixed.
Are the rocker arms by chance from Michigan Motorsports? If so, this type of thing has happened before. Go to the junkyard, grab some stock truck 6.2 rocker arms, and do the trunion upgrade yourself. The oem castings are way better, even used.
Fuck that thing is probably one of the best sounding builds of this motor I've ever heard; I cant imagine what it's like in person with it actually thumping your chest.
Man surely out of all the engine builders and ls guys y’all know some ones got some rockers you could snag. Well least I hope so. Hang in there brian they car really improved.
I dont know if its the same over there in the states but over here in Australia we had a recall on ls3 and lsa powered vehicles due to failing oem rockers. Possibly got a set of faulty rockers and if i remember correctly it was the intake rocker arms that had the fault and it looks as if you broke an intake valve spring.
i feel like i heard that arm jumpin around at the end of the 1st power down pull. i thought it was a knock for a second and then didnt hear it when you went for the next pull. B reminds me of myself a lot in the car world, literally every big piece of progress comes with a setback. itll come together soon tho!!
GODDAMN Brian has the absolute worst luck in the universe. Can't wait to see him actually rip this thing. Sounds so crazy and is gonna sound even crazier when its flying sideways. Love the content boys, been watching forever.
Those looked suspiciously thinner than stock... if you still have your stock ones or can get a set and the trunions are actually upgrades its a pretty fast swap.
Hawk Speed & Custom actually steered me away from Texas Speed in terms of anything except their camshafts when shopping for LS3 parts and I kind of ignored it a bit, until seeing this. You guys remain sooo positive its crazy! I cant wait to see 500ftlbs!
Dang sorry that happen Brian but it could have been a whole lot worse! maybe TX Speed can overnight you guys something to get you on the road. At least for the weekend??
I'd add some hood louvres for heat dissipation. That is a tight engine bay, not much room to get air around the engine, and when you are talking this kind of HP you are also talking heat. Every high end performance car should have air scoop and hood louvres I think. There's some direct air injection. lol Personally, I'd keep it around 420 HP myself and not try to extract too much out of the engine. Running 8/10 tenths power is more than adequate.Will help in the longevity of the engine.
Not to argue but you can find out if a cilinder is misfiring. I saw in the "naughty stuff with the 86" video by Phil Morrison (Driftworks) that they took the temps of all the cilinders while it was warming up idling. The misfiring one stayed cold. This Beamer is getting so sick. Can't wait to see more of it
Felt sooo heartbroken for B when I saw that puff come out of the breather. Definitely clinched my cheeks. Was hoping it was nothing but I’m glad to see that it isn’t that much damage. You’ll get it sorted between Texas Speed or Bootleg I’m sure.
It could be that you are hitting coil bind or are very close to coil bind. OR your springs are too high installed pressure. The OEM rockers are known to take .750+ lift. I would dig in to how much preload you're running on the lifters, and the aforementioned factors before you blame the rocker body.
