Hey guys I need some help and advice . Bought a set of 360.1s from a member here with little run time on them. Put the heads on with new springs and retainers . Made a few great passes and they done good. Fast forward to today. Nice day decided to take the car on a little warm up drive around the block. Heard a heck of a noise and coasted back home. Exhaust rocker broke into at the shaft area. Is this a problem with the blue Indy Rockers ? I called Indy and they said call them back Monday to see if they had any left in stock . Discontinued .. Options ? , advice . Thanks..

They’re decent for a solid lifter or mild solid roller. Thanks , I have never broke a rocker before. My cam is a solid roller but not huge. 6.52 lift. Scared the mess out of me..

From what I recall, the 360-1 rockers are the same as the 440-1 rockers. Different spacers and shafts. The exhaust rockers are the same as the intake/exhaust rockers for stock or SR heads.
If Indy doesn’t have any, I’d think with some hunting you could find some used spares....... but I’d look at that broken one as a sign of things to come.

Why do you think Indy doesn’t carry them anymore?

The easiest to get “good” rockers will probably be T&D.
Hughes might offer something for those heads...... just check their site.

I'd say step one is correct your geometry. I'd bet good money the geometry is off.
Fix that first. That rocker should live forever for what you're doing.

Look up his site and read the tech articles. Then order the kit.

Been there, done that. Just change to T&Ds now and save yourself some frustration.

I have a full set of black 1.5's that have never been used with a roller cam. If you're interested in the set let me know.

ok Yes they can be prone to breakage when used with roller cams. Typically when one goes there tend to be more afterwards. Yes they were made by Dove but they went our of business or were bought out. Those are a 1.6 ratio if they are blue and 1.5 if they are black. They are the same as the big block rockers so you need to know if you need a left offset or a right offset. (which side is the adjuster on). I should have some spares if you want just one. IF you are running a roller I would invest in some better rockers, Harlands or T/d would be your best bet. They were made from an extruded aluminum and for sure have a cycle life like most aluminum parts.
Todd Hey Todd I was was going to try to call you today to see if you had some in stock. I really need to make sure everything else is okay on the engine so I would like to get a spare to make a set anyway. Dude at Indy said it was the exhaust left rocker. That confused the heck out of me as all of the exhaust rockers look the same to me ?? You going to be open today ?

Guys here found a cracked one on their SR headed wedge, only running a very mild solid roller, changed to HS rockers.

If these are prone to fail then I def want to change them.. Could you guys send me the info on your rockers and price ?? Thanks so much.. Just asking again because it matters. Have you corrected your geometry or at least considered it may not be correct? I'm not saying you shouldn't change your rockers out. What I'm saying is is the geometry right. You can fail many quality rockers if the geometry is wrong, and 99% of the time it's anywhere from marginal to straight wrong. I did a low deck with 440-1 heads and I was doing a mock up with the springs I was going to use and broker a rocker turning it over, by hand. I looked the rest of them over and I couldn't see a fracture on any of them, and the fractured one looked like a clean break. I ordered a new rocker from Indy and asked him how can I be using his heads, valves, his rockers, his installed height numbers and the geometry suck so bad. Russ told me either I had something wrong or I was stupid. So I corrected the geometry, it went to the dyno, made 770 HP and went in the car and ran for three seasons until that customer died. Just putting this out here, because it needs to be said.

Just putting this out here, because it needs to be said. I appreciate your input on the geometry and agree 100% with it. I run through the way the rockers were riding on the valve stem all the way through the range of motion. Very close to perfect all the way through I did find that the pushrod end was really close to the rocker arm by design. No contact but very close. I am no wizzard with these rockers and the Indy heads but I think the geometry is good. Thanks for your input again.. always helps to have a different opinion..
