Ive saw my share of them broke, similar to 97-98 Ls1s...junk

 

My 05 LQ4 6.0 had the better cracked rods, It was sold to me as an LQ9 so the guy thought because of the rods, but when I pulled the heads I def had the dished pistons.

 

What failed? Crank? Rod? Pistons break? It can't all be junk.

 

The 99-00 6.0s also had iron heads

 

I'm aware of that. I have a set of heads for it already.

 

Rods are junk

They dont like rpm or power

 

If you insist on keeping stock rods and pistons get a GEN IV.

 

Sold the t56 and picked up a 4l80e for a core or to be built. Been looking at Monster for the trans. Thinking about the 750hp/700ftlb setup. Any other recommendations? Shopping for a forged rotating assembly as well.

 

Heard bad things about monster.... Heard good things about a few of the sponsors on here.... Im sure one will step up and give you some advice or set you in right direction.... I personally vote for build it yourself..

 

I don't have the time to learn how to build a transmission.
