Default Connecting Rods Question

Ok guys, when changing out my intake manifold I must of gotten some radiator fluid down in the #2 cyclinder, and it caused it to bend my connecting rod. I know this b/c I had a compression check done on it.

When ordering new connecting rods online, which kind does everyone prefer? Best Performance...etc.. Where should I order them from?....etc.... The engine is basically stock other than CAI, steeda pullies, and intake manifold. 4.6L, 2V engine.

Thanks for your help guys.

I'd say the Manley H-beam are by far the most popular forged rod. I also have some cheaper forged rods (Modmax) for basic econo rebuilds.

My advice is that if you're going that deep into the engine, you should forge the entire thing. The biggest cost is the labor, so go ahead and sink a little more in it and get a forged crank and pistons. Any forged rod is better than stock. The Manleys are great, Probe and Eagle are both good too. It's a preference choice. The HP rating is what is most important if you're going for big power.

The types of steel they advertise, like 4340, does that make a difference also?

Water does not compress. So when the piston comes up on the compression stroke it will not beable to come up as far as normal and cause the rod to bend.

You must have gotten alot of coolant in that cylinder for it to bend the rod. You might want to tear down before you order anything. what was the compression in that cylinder compared to all the others? What steps did you take after you saw lower then normal compression in that cylinder?

I am running Modmax 4340 H beam rods. Rated at 1000hp, we'll see.
