Questions for 418 stroker with Forced induction
hey guys, new to the forum and honestly most chevy aftermarket LS stuff but hopefully some of you can help me out with some questions I have!
So here's the run down. I have a 2013 stock LS3 that has probably 1000 miles on it that was pulled out of our 6100 race truck, the motor was pulled because it sucked a slight amount of dirt in it and was cut because we obviously couldn't finish a race with a motor like that so it was stopped early. We pulled the heads and it wasn't too bad. but regardless the motor will have to be gone through and taken completely apart which is fine. I picked it up intake to pan for cheap and have basically nothing into it and want to make it a fire breathing monster to go into my tube chassis prerunner. my questions are as follows.
1.how reliable is a 418 stroked motor granted the parts are top notch from texas speed or LME?
2. can the block handle big power? what is "pushing it" for an ls3 that has forged internals
3. is 500-600rwhp achievable NA or should I build it knowing I need to be FI to reach my goal.
my goal is to have a 500-600rwhp truck that runs 39" tires and weighs close to 5000lb. This truck wont ever hit drag strips or anything that most of you might be used to, and reliability is a key factor. I can't be 200 miles into the desert and boom goes the motor because I wanted something unrealistic out of this motor. I will be running a turbo 400 trans that will connect to a Currie full floater. Below are some pics of the motor itself along with the truck it is going in.

was that NA or forced? I've been told I will lose so much through my drivetrain that it disheartens me ha. I don't know how true that is so maybe someone will be able to give me some real numbers or real % loss that they experienced.

so i've been doing some reading up on this motor. and seeing that its aluminum I've read that at higher hp the heads tend to lift? can anyone verify that? is that something I might come across when building this motor? are there any remedies?

As cool as centrifugal superchargers are, like ProCharger and Vortech and such, a positive displacement supercharger, like a Maggie or a MagnaCharger, would be quite fun in that truck, as you'll have the power right then and there when you need it. With the motor built right with quality parts, it can be pretty damn reliable, especially at your power goals. I've spent my time in sand and mud and damn would that power have come in handy GM build's 500+ horse motors, such as the LSA and LS9, and look how reliable they are. You shouldn't run in to any head lift issues either, especially not with a set of ARP studs like stated above. Good luck on your build, sounds like a fun project!
