Took the blue vette to PRP last weekend, everything seemed fine… but noticed the pass. side bank poppin almost like a miss. Revved up fine, didnt get hot or anything, so I ran it.

Maiden voyage, 10.73 @ 125… foot braked it and short shifted it. Noticed it breaking up a little after the 2-3 shift. 2nd pass… was breaking up worse, so just shut it off.

Brought it back, pulled valve covers and found 2 of these:

rockers just spit the roller bearings all over the place! Some of the others were loose as well. Anyone ever see this kinda failure? This is a 482ci, 800 lift cam, mag. pushrods, double wound race springs, etc.

Ended up buying wide body race crane rockers for like 445$ :rant:

Can you buy individual rockers? I have good ones left, would work for a street car…

2

are those harland sharps…if yes then you can from harland sharp

3

Ouch. Looks like they couldn’t handle the spring pressure. What ratio are they?

4

damn

5

are harland sharps guranteed? i know this happend recently to another member and contact harland and they sent him new ones…

i cant view the pic but i know he snapp the rocker in half

Wow, that sucks, i have found that the sharp rockers have very narrown needle bearings in the fulcrum, I killed a set on my big block just street running it with 280lbs on the spring seat… I went to a set of crower S/S and am very happy…

7

that sucks

8

those actually look like crane cams gold rockers to me.

9

yeah, they are crane gold race’s. I talked to summit and they said there was no warrenty on race parts.

They are 1.7 ratio. The valve springs are 230lb seat pressure.

10

10.7 is slow

11

Ouch! That comment hurts!

12

Ouch … Sorry to see that

13

might go out next weekend to see if everything’s ok

14

19

Great movie. The black T/A in that movie was sweet too.

20

I guess its worth a shot. At least they could be used on something else then.

…the summit guy though was pretty certain sounding that there’s no love at all for racing parts. :dunno:
