Aiming for 500 WHP, any advice? Hi,
I'm working on my LS6 engine right now, and just like the title that I put above, aiming for 500 hp on wheels.
So far these are parts that I have bought.
- Forged bottom end (K1 crank, Lunati rod, 3.905 Wiseco piston).
- PRC 227 heads, 62cc chamber.
- Comp cams, 231/239, .617/.624
- Morel 5206 Lifters (I have Comp short travel lifters as well, but I think Morel will do the job better, right?)
- TSP roller rockers.
- Holley single plane intake.
- Holley 4 barrel 1000 cfm throttle body.
- MSD coils.
This motor will sit on a weekend warrior C10 truck with a TCI 4L80E 6 speed transmission, 3.73 final gear, and 27" tall wheels.
Any idea how far I am from the 500 hp that I aiming for? Any advice on what parts that I should use or replace?
I'm thinking about swapping my cam with something that a bit bigger, any advice on that too?
Thank you.

Wheel HP or flywheel? Title says whp but question at the bottom says 500hp. You're about 75 whp shy of 500whp. 500whp stock cubes through a 4l80 and 27" tire is a tall order. Consider boost?

Stock compression pistons? If so, the forged rotating assembly isn't helping you to your goals at all.
Neither are the MSD coils.
The roller rockers are still on the fence depending on a few variables.
You're basically left with a head/cam/intake LS1. I agree, 75whp short with the 80e and that intake manifold.

500 is going to be a tall order, if not on the verge of unrealistic through a heavy 4l80. We have made right at 500whp with The following parts through a stick:
-Mast Heads (Milled)
-Vindicator Camshaft
-Johnson Lifters
-Ls3 Rocker arm set
-Fast 102
-102 Tb
-1 7/8 headers and supporting exhaust
This combo was not the most street friendly either, so keep that in mind as well. Let us know if there is anything we can help you with.

Noted sir, 425-ish WHP, I’ll be happy enough with that number.
As for boost, i’m not really sure about it.
Thank you.

So since the shipping cost would be pretty much the same if bought another stock crank I decided to bought a forged complete rotating assembly, and on that moment I didn’t have any goal about HP in any kind of way, just want to make it run again, and cosmetically looking like a gen 1 motor, haha
Considering this is my very first time working on my engine all by myself, I will take 425-ish as good start
thank you.

Sure, I’ll let you know if I might need something

Its possible. It will just suck to drive.
My buddy did a 4.8 that made 600 at the crank on his engine dyno. That would be 450-470 wheel depending on drivetrain.
A 5.7 would certainly make it easier to do, even with an auto.
Nothing is impossible, but sacrifices will be made.

Now a 480 hp will beat a 500 hp stick, so track goals matter more than power goals
522 to be exact. that motor is in my car today. 12-1 compression. He rebuit it a couple of years later with a 6.0 block and it made the same H.P. numbers but the tq. was about 30 higher

What were the heads/cam used? Stock pistons? Can't find much info, would be cool to read it.
