wtf.. lol

This happened in a 3400 yesterday after only a few minutes of running.

Cam is .506 lift, all the other springs have roughly .060" before coil bind.

Were those from Ebay? If so, it doesn't surprise me one bit.

I was just going to ask if they were ebay springs....

Is this the same guy?

Yep, they had the blue tags as well.

[923.4v6]

Blue tags say made in germany.

WTF indeed! I got your message this morning and I will go make sure but I should have an extra spring lying around.

[candychevy87]

wtf, just compressing the spring shouldnt cause it to break, did the pistion hit the valve??

[Superdave]

i don't think the engine ever saw over 2500 RPM.. lol


Ben, i think he scored one on V6Z24, i'll find out for sure later though. Thanks for looking.

Your going to keep the rest of the springs after than happened?

[ForcedFirebird]

The GM yellow springs should be good at .506"!??!

Your going to keep the rest of the springs after than happened?

He likes to gamble..

it's gotta be running for the V6 bash, that's why we're pushing so hard. poor guy pulled his stock 3400 and stuck in the built one.. it spun #4 rod bearing after a few minutes ( the block is cursed).. so he had to pull it again and put the cam and P&P'd top end on his first 3400.. now it breaks a spring.

ouch yeah cant say any of mine look like that. last time i saw mine they looked normal.
i found this awhile back dont know if id totally trust them to 550 but 500 they should live for awhile.

GM LS6 Valve Springs

Designed for lifts up to .550" with less aggressive ramps!

For springs designed for more aggressive camshafts take a look at the Comp Cams 918 Springs or the Precision Race Components Double Spring Kit!

Wow. Try to take some detailed pics when you get it out, im willing to bet there was some type of flaw in the metal from the factory.

busted shit FTL!!!

i went the race track sunday(9 days ago) and ran a personal best, 14.71, with a stock 3400 in my bird.... went home, ahd the motor out that night, and from there everything sucks :P swapped it, blew it up, pulled it again, swapped parts, dropped it in, broke a spring, got a new one from GM(had the blue "Made in Germany" tag on it), put that in tonight.... it has a gross-sounding top end clack also.... so tomorrow i get to pull the timing cover and make sure the cam bolt it tight.... because we checked all the rockers, that's when we found the spring, we were searching for a misfire. Misfire's gone but it's waaayyy to noisy... so i'm doing that tomorrow.... man..... what a week.... add in my GF breaking up with me and kicking me out of the house, and i stopped having a good time last monday night
