500hp N/A
#1
![Default](https://ls1tech.com/forums/images/icons/icon1.gif)
I'm somewhat new to LS1 TECH and I, of course, want to achieve more power from my car (in sig). I was wondering what type of heads/cam setup ect. I would need to go with and what other mods I would need to make around 500hp at the wheels on stock bottom end with no power adders.

What kind of drivability do you want?
I had a TREX cam with stock ported heads on a 408 with mid length headers and it made some damn good power, never got it to the dyno though. Only down side to a big cam like TREX is you would need a different torque converter.

It's doable, but it's not going to last very long. Not going to be a 100% stock bottom end, flycuts/rodbolts, gonna need to be a solid roller also. If you get enough compression and can cut enough of the piston and don't mind really spinning it. I'd say its falls into the realm of possibility.

I wish u a good luck man in acheiving your goal , but I am sorry
to tell u that is extreamly difficult ....NO WAY ...in short words . It is a good thing that u have a dream , but u should be reasnobale 500 hp N/A
, If you r right u would see many N/A 450+ hp , and I well be the first guy to do that . If you r correct , the need of a larger displacement wont be needed and the ls1 will be named as the rocket engine . I wish u reach what u want , but before that , do some research , modify yor knowledge , and I am sure that few mods will put a big smile on your face ...

Lee's car had a TH-400, a huge stall, and slicks on when it dynoed that number.
To do that with a stock bottom-end would be an accomplishment. It would get much easier if you re-built the engine with good pieces. A solid-roller valvetrain would make it even more do-able, given that the solid-roller valvetrain is setup properly.

nothing is out of the realm of possibility but its not even worth attempting somthing like that with a stock bottom end. a 383 or 402 would provide a much broader hp and tq while not having to spin the **** out of just to hit 500rwhp. add the fact that it'll be a race gas only setup and pretty much regulated to the track only.
i finally fired my **** up on friday. im working on tuning gremlens now.

Thanks for all of the responses guys.
I was actually looking to see if it was possible as well, so I guess that question is out of the way. I now realize that to make big numbers in that range I'm gonna need lots of work. On the other hand since 500 on stock block is far from possible i would also like some suggestions for a good heads/cam that will bring me to the most power I can achieve with really good driveability. My car is currently a summer DD and I can drive it less but i'd rather have it be reliable enough to drive daily during the summer months.

anything is possible so long as you have the budget - case in point, NASA made an ink pen that works in zero gravity when all they needed was a pencil.
I have no idea how you'd go about making 500rwhp on a stock bottom end, but I would say start by researching what everyone has done to date, then think out side the box. All you need to do is come up with the right combo no-one else has thought of yet
