LS7 Ti rods vs Steel rods?
Hello everyone. I'm building a 383 using an LS6 block and LS7 crank with the LS7 factory dry sump system. My goal is 500rwhp NA (possible supercharger/650rwhp down the road) and 7000RPM max. I need some advice/input on the factory LS7 Ti rods.
I have the option to pick up a complete set of LS7 Ti rods for $400 (10,000 miles and checked out as ready to use).
For about the same price, I can pick up a set of forged rods (eagle/scat/etc.).
Which is a better rod to go with? Why? What are the advantages/disadvantaged to each (obviously Ti is lighter)?
Thanks,
Chris

??? what? I don't understand your question (well I do, but what does that have to do with the rod choice?).
I am aware that the LS7 crank is pre-balanced for LS7 rods, so steel rods could/will required more heavy metal. But I'd rather pay more in heavy metal if it means the engine lasts longer (doesn't kick a rod).

Both are different rod lengths
Your LS1 connecting rod length is 6.098 inches.
The LS7 Titanium connecting rod length is 6.064 inches.
They also have to remove the reluctor and have a 24x reluctor fit. The piston pin diameter is .925" on the LS7 rods and .944 on an Ls1/6 iirc.
But I'd go with an Hbeam rod and ditch the Ti ones.
Just my .2 bud.

I'm running the 58x reluctor to work with the 2010 camaro ECU/harness/etc.
Why H-beam vs the Ti (just because of the rod length issue?)?

The titanium rods don't exactly drop right in, but they work with just a little bit of machining that needs to be done anyways.

What they're trying to tell you is the LS7 rods will require more work and money to install. The difference in rod length and piston pin size will require a custom piston. You can buy an aftermarket crank, rods, and pistons that will work well together without breaking the bank.

Sounds about right balancing cost can spiral out of control quickly. The LS7 Ti rods is a sure bet to save you some money. Cheaper to remove metal from the crank than add heavy metal. Considering your smaller pistons should be lighter than the LS7 OEM pistons.
