How much power to expect? This is my first post so please be patient.
I am half way through my first ls build and not really sure what kind of power to expect, and also any help is appreciated. I started with a iron lq4, and sent it to performance clinic in xenia ohio. Ordered a callies magnum crank with a 3.85 stroke, and a set of ultra xd rods, Ross pistons set up for 9.5:1 that were coated for heat. The cam is a hydraulic roller, .618 .613/ 283 288 on a 115lsa. Tfs gen x 255 cylinder heads, and 2 gen2 6266 precision turbos. That's all I have bought right now, tell me if im headed the right direction, and where I should be on power. Its going in a 08 rcsb silverado with a 4l80e

What fuel?
How much boost?
Converter locked?
Honestly I would have went bigger on the turbos. You'd dumped a lot of money into that combo, you don't want the stock short block guys making more power than you..
The Performance Clinic guys are good. They maintain a car for a friend of mine.

Ok thanks, that's a good start, it's going to be on the street alot, so much more than that is going to be tough to keep in check. Do you think that short block is capable of more boost and power without having trouble?

Yes. With the amount of stock short blocks out there over 1000 HP, you're going to be limited what the iron block itself can handle. With a longer stroke, I'm going to guess you'll be limited to either what the mains can handle or the clamping force of the 4 bolt heads.
