454 (L29) Cam Suggestions

Sure, you say that now but, wait until later You'll wish you went bigger

Typically I agree with your sentiment, but I have a bike and a car that tick the "need for speed" boxes, and a truck that gets used as a truck. The dually is just a cruiser. It ain't gotta go fast or drag a heavy trailer. It's gonna function as a work in progress until someone decides they want it more than I do...

So it turns out that a pushrod got sent through the rocker arm on #2, and there's a bent pushrod on #8
Can is good, so lifters, pushrods, and rocker arms are ordered.

Well that's easier than a cam but still a bit catastrophic. Any idea why?

When I bought the truck it ran, but ran ******. Figured with the low mileage it had sat and had nasty fuel in it, so I dropped the fuel tank to drain it and discovered a pretty big hole. Also, the fuel that came out of the tank had a high water content.
My theory is that they filled with water and hydrolocked.

Here's a couple of pictures of the damage.

If hydrolock was the cause, I'm blown away by the fact that the valvetrain took the hit and not the pistons.

I'm not convinced it was, but that's the only thing that I can think of. I've seen hydrolocked big block pistons survive intact before, but I'm far from 100% on what actually caused this.
Only thing I know to do is put it back together correctly and see what it does.

And then do a compression and leak down test.

Agreed, that's where I started and where I'll end.

Not meaning to threadjack.

Any cam recommendations for my stock L29? I'm adding Five-O injections, blackbear tune on an 0411 swap, longtube headers (3" true duals installed). Mainly used for light work and will occasionally pull a 8-10K travel trailer. 153k on the motor, runs well.
