That is the first negative response I have heard so far. Most people are saying that they are pretty good. Good info though. Trying to make a decision.

Yep ^^ Seen lots of threads on tech with the pushrod cup snapping off.

From what I've heard they have less issues than Harland sharps.

There have been around 10 sets I have seen that have had the pushrod cup break off.

I would run trunnion upgrades on stock rockers or jesel rockers.

supposedly that was a bad batch of yellaterras from what i've found. i'm considering doing a trunion upgrade on mine but i really want the roller tip

I forget, can you run the trunion upgraded ones with a non factory valve angle?

Ed Curtis recommended stock rockers, with a trunion upgrade, to me for a 244/250 .638/.624 cam when I asked about aftermarket ones.

the ONLY ed curtis cam i've seen that made any power worth a crap and ran was the tigershark cam that jeff goodell had in his blue gto. other than that i think a freaking 228r would have been about the same or better.

Couldnt have anything to do with the rest of the setup could it? Grangers car had junk heads, cheapest headers you can buy, zillion mile probably slipping transmission, exhaust thats barely adequate for a factory car, etc. Cant base it off one good build and one half ass build.

Ive heard they usually only break when you spray the car, so yours should last forever.

I've been on yellow bullet and it has been the exact opposite of people's opinions on here. They say good product and great support.

A lot of Austrailians on the Bullet. I am sure the support is great down under.

Will be a lot of support from me too if they work out and for the cost. Nothing ventured nothing gained.

But they break on LSx motors so they must be no good on anything else...
