Connecting rod

[New2dodge]

So I installed my connecting rods this weekend and whenever i torqued them down i couldn't spin the crank. Has anyone ever ran into to this before? Spins fine until i torque them and then can't move it at all. engine is a 4.7l

Did you plastigage the rod bearings? Did you center the crank?

Are any of the rods facing the wrong way? That will do it.

Locks in the right place and seated? Not undersize bearings in a standard box?

I didn't use plastigage. I will go get that today. I'll check the rod and make sure they are all facing the right way. I'm pretty sure they are. Thank y'all for the replies. I was reading somewhere that the bearing could be backwards but there isn't a tab on them like the crankshaft bearings. How would you know if they were backwards?

Sorry to say this, but if you have these kind of questions, maybe you shouldn't be elbow deep into your engine.

Unfortunately I don’t have much of a choice. I don’t have the money to have someone do it for me. So I’m trying to learn. I’ve done engine work before but never anything to do with the pistons and crankshaft.

A simple mistake can cost you an engine. Think about that when you decide what you can and can't afford.
