Adding a bit of a "contingency" incentive to this bad boy, check out the info in the first post. If you're planning to make some power in 2014 you will not find a better deal!

@TXMaro until someone buys this bad boy!
@86lxnotch We're ideally looking for whp, I had figured in 20% drivetrain loss for the auto guys so 1500hp at the crank. I suppose an engine dyno would work, that would be $2.80/hp in excess of 1000

That makes sense, we're more chassis dyno guys so typically any hp figures we're referring to are at the wheels 
In regards to the limitations of this shortblock its hard to say as there is a fairly limited sample set to work with. I suppose the weak link would be either the block or the factory main bolts/studs, but you would be way up there lol.

They will be added in the near future, but it is quite time consuming. Please feel free to PM us for other applications, we're in the process of building a beast of an LSX for a late model CTS-V and quoting an LM4 build for another customer
We also just swapped 6L90's into both a Colorado and an Avalanche but that's a bit off topic for this thread lol.
