God damn...

Who's push rods are they?

Dunno, from what little I understand they were ground in house. And obviously "custom" ground.

that Blows!

VERY POOR QC. or a inspector who is hung over or just doesnt give a f#ck what goes out the door.:eek2:
some of those look to be at least .050+

We measured smallest to largest .060 :mad:

WOW....are they going to refund/fix/help anything? Or did you already destroy the bodies?

We tore it apart, two cam lobes gone, morel lifters shot, wrong size springs; max lift before coil bind was .70, dummies installed a .73 lift cam, pushrods speak for themselves. It's a situation where I took it to a shop and they outsourced the build to Westech.

The shop has been great helping me track all this stuff down. I figured out the coil bind with a spring micrometer, they discovered the pushrods. The shop is covering this but since Westech was their agent it's up to them to go after Westech.

This is the 2nd time this happened, the first time wiped the LSX block and most of the internals. I paid for that..... I'll deal with that once this thing is put back together correctly. It's in good hands now thank god.

That's the short story.

name sounds familiar, i believe there dyno are used in alot of printed mag articles for results.

I guess if you want something right you have to do it your self, to many people think S*@! like that will work.

Damn, good to hear someone is getting things covered by the people involved, which is both the shop and westech's fault.....without having to argue back and forth for months who's at fault.

Hopefully that shop will start using someone else, Westech is pathetic for doing that.

Good customer service by the "shop", bad choice of builder.

Wow, at first I thought they just weren't set evenly at the top. .060 off is a lot. You could look at them and simply tell they are different links. Good luck with getting it back together.

WTF ?? That's rediculous..!

HOLY WTF!!!! somebody would be trying to shat that sideways...jesus that is pisspoor QC work period...i hope it all works out for you!!!

What rockers and lifters are/were you using?

dammmm.

What rockers and lifters are/were you using?

Morel link bar solid roller lifters, T&D roller rockers, billet camshaft. We couldn't lash the valves and that's when we pulled the pushrods and discovered the different sizes at which point I just about shit myself. Im surprised it ran as long as it did.

I think this is in part to the non-adjustable valvetrain. Old school cams - and current solid rollers - MUST have the exact length pushrod to work correctly. My guess is that with a non-adjustable valvetrain, someone thought that all the lash/slack was taken out and it didn't matter much if there was .060 difference. Put 'em back together and see if they don't all snug down to the point where they depress the plunger a bit...
"Hell, that one's good, send me the next one"...

^ I am pretty sure TD only makes adjustable rockers for the LS series of engines. He mentions trying to set the lash, but was having issues. That's when they discovered the pushrods being out of whack.

WOW,thats pretty scary. Well im glad to year your getting takin care of though.
