Wish I could answer that but it being said, What’s wrong with the brand of pushrods you have now? I’m sure you know, this is unlikely to blame on the pushrods.

Well I’m getting 16 pushrods cause I don’t want to replace just two. Just wondering

Wait and see what your builder finds.

If the pushrods simply came out, your rocker arms were misadjusted (loose) and turned or rocked enough to allow the pushrods to slip out. That ticking you heard may have been loose rockers.

If the pushrods are bent, then you had mechanical interference at play. Valves may have bounced and kissed the piston top or your rocker ratio and pushrod pocket offset may have caused your retainer to hit the guides. Things like valve spring coil bind need to be rechecked and ruled out but typically, you will also have a broken valve spring from coil bind.

+1 to this.

Definitely understand that as different lifters will likely require a different length pushrod. Do you have the build sheet for your engine? May say the brand and wall thickness of the ones you have now.

Wayne has it. I’m hoping this goes smoothly and I can be back on the road in about 3 months. Will definitely be getting and MSD box with rev limiter

When you get the rockers off, take a pic of the tops/tips of the valves, can see if the pushrod length was a factor. Might as well take a pic of the bottom of those rockers on #2 as well. Or a few of them.

I would say the most likely cause is retainer clearance, but if that's the problem, it's going to be a builder issue, and he may just do the same thing over again. (since he didn't check/catch it the first time).

Smith Bros pushrods are pretty good, and pretty affordable. Butler sells them in lengths of .050.

Some people prefer thicker wall ones, or larger diameter which requires changing the guide plates.

Rev limiter? Do you think you over-revved it?

Just to say, over-revving is generally not a cause of bent pushrods.

Here it indicates he was planning Lunati (unknown specs) pushrods...https://forums.maxperformanceinc.com...&postcount=165


Hopefully you get this all resolved with minimal damage!!

Yeah I over revved it. I missed 3rd and it hit about 7000. Caster1 has almost exact engine in his car and has no problems from it. I am pretty sure I over revved it and that was it. It holds 10 pounds at idle even coasting down the road and ran fine other than a skip from the dead cylinder. I am hoping I can drop the pan, clean it out, put lifter and pushrods in and seal it back up.

Lifters probably came out of the bores.

Like I said, over-revving rarely causes a problem like this.

What was your oil pressure prior to this issue?

25-30 hot at idle

More red flags from that post....

He will be providing the Lunati pushrods, oversized cam bearings, and all gaskets except for head. I think that’s a hell of a deal. What are your thoughts?

Looks like he's a Chevy/Chry/Ford guy:

Wow, more than a few left crappy reviews:

Is this the engine with big Chevy rockers because the machinist determined Pontiac rockers had incorrect geometry?

I missed that point, what's the post # on that? Or different thread?
