As slowhawk said, there are very few ls1 shortblocks with 500rwhp n/a.
Maybe a handful with huge h/c setups.

500rwhp is usually from more cubic inches and or a poweradder.

Huge cam setup and good heads. I am ONLY making 473 rwhp and 431 rwtq, but keep in mind I am using the 78mm Fast and a 78mm ported TB with the G5X3 cam. Had I went with the G5X4 with more lift and a little more duration, and the 90 mm FAST and 90 mm TB LG claims I would've seen 503-508 rwhp with 450 rwtq . Probably would've required porting both the intake and the TB though. It just got to be too expensive, and also at what cost to the longevity of this stock bottom end motor? I will be upgrading down the road to the 90/90 combo when its time to replace my valve springs. Will post the new numbers for comparison. Read my sig for what it takes to get to 470 +. More cam and more flow would've got me to the 500 rwhp you are asking about. Hope my sig helps you out. GOOD LUCK

507.9 RWHP here. on 346CID

STOCK LS1 BOTTOM END

Just a set of ported LS6 heads, a cam, and the usual bolt ons.

it looks like you have decent bottom end torque also with that 508 hp.

I do. I was very surprised how much low end power the car makes. Very streetable. I love driving it to the shore with the tops off.

cmon... a LS2 is not that much bigger than a LS1.....


I made 513 with my setup....

So swap my setup over to a LS1 add an electric water pump and you should have damn close to 500 rwhp....
