To "swap" a set of rods properly takes balancing, blueprinting, possibly crank work/bearings. Unlike what our crazy old Uncles led us to believe growing up, motors aren't like lego sets. Yes you can just throw a motor together in your garage over a weekend... but just because it fits together doesn't mean it's right or a good idea. This is how people end up with "rebuilt" engines that last 30k miles then **** oil everywhere and start knocking.
I'd recommend getting a different engine if PMR rods are a concern, or have a competent professional rebuild what you have.

Stock power on PMR is not an issue, but good to know what is in the motor. PMR can put out lots of power, just need to be aware so the tuning can
be set with them in mind...

You make it sound so easy!

Balancing isn't even an issue as the crankshafts are identical between forged rod engines and powdered metal rod engines....unless one desires to do better than the factory did on an engine that might see 3300 RPM a few times in 400K miles.

It would probably take about as much time to pull the motor as it would to take the valve covers off (in the truck)

"Why cant you pull heads and swap rods and piston's from the top? Without pulling the whole engine out"
Because it is nearly impossible to do properly and have no oil leaks as well. For someone that has the experience and proper tools it is probably quicker to pull the engine.

Really? I never thought that's what swap ment. So what would you call it then? He already has the engine out of the truck which is half of the battle, but in the OPs case I think he will be fine with PM rods.

I understand it is out now. But I do know you can pull out the oil pan. We did it on my brother in laws truck when his flywheel cracked. While there we pulled rods and main bearings replaced with new ones. The mains were a bit more of a pain but got it done.

Was it knocking? Replacing bearings without taking everything in to get mic'd and resized if needed can be worse than leaving the old ones in. Hope it worked out...

To be fair, his question was answered in the first couple posts.
I'm carrying it on to help mitigate the future newbs from pulling this thread up and thinking it's a good idea tor that it's easy to swap rods out in the truck.

I just did a engine swap about 3 months and used a 2002 van engine in my 2000 F350. Being a van engine a lot of the accessories were different so had to swap some stuff but if you have a truck engine it should be pretty easy. My engine had bad compression to
