Ls7 ' s came with titanium rods that are about 460 grams, aside from adding a bit a mallory will there be any issues balancing the rotating assembly with say manley pro rods and wiseco pistons?

Bit of Mallory is an understatement....

Just had a friend balance and LS7 crank to a set of the Ultra H beams and a set of wiseco pistons....

Took 7 slugs of mallory and the bill was 900 bucks. Put the cost of the crank with the cost of the balancing.... and you can buy a 4 inch stroke Dragonslayer from Callies with the LS7 snout for the same money.

Well scratch that then, thanks John

Yea, the titanium rods kill it.

Done about 10 of them and they are trainwrecks if you don't keep everything really light like LilJohn says. Usually you can get a new balanced crank for less and sometimes a decent amount less but sometimes its not really really bad just pretty bad.

Can you keep the rods and just swap pistons?

I'm not an engine builder... Wondering. I would think titanium is light and strong... Why not keep them?

Sure but not a lot of shelf options although Wiseco has a few. You can get a custom piston as well so that they are about the right weight to balance back out of you know what the old pistons, pins and rings weigh.

As stated above, they suck to balance. Buy an aftermarket, or get a piston to go on the factory rod. Just be sure to upgrade those rod bolts.

turned away the last one...................let the guy face the fact that a new purpose built crank is cheaper and stronger.l
