I improved the 441/393, to 450/407 switching out the 2OTL catback.

Not sure the specs but found this posted, also found .610/.615 posted
"244/250 Custom Grind" "Comp X-ER"
"Lift is around 620/625 110 LSA"
Peak TQ was 400. The TQ curve is flat from 5,000 to 6,000
with and without vacuum pump

The LS6's with a cam like that and the SSHT style 228/232 and bolt ons make some get power. 420-440whp 400-410wtq rock.

This is an interesting thread, but most of you are saying a 300-320 horse LS are now making over 500hp at the crank with just a cam?
Whats even more interesting is Texas Speed told me their $2000 top end package making 525-550 HP...so how does that make sense?

found this one
2001 C5, stock 346 LS1
Street Sweeper cam package
American Racing 1 7/8" headers
New Era ported throttle body/ LS6 intake
Tuned by Mike@newera
426RwHP 387wTQ![Headbang](https://ls1tech.com/forums/images/smilies2/headbang.gif)
Peak power at 6300, great for a street driver stock LS1. And hold to 6800 if you want to rev there.

That being said, most of the cars that hit the 400 rwtq mark with "cam only" have supporting bolt-on mods to go with it (full exhaust, an LS6 intake, underdrive pulley, ported TB, dyno tune, etc.).
So yes, it's taking a LS1 motor rated between 320 - 345 hp at the crank (it's understood that these cars were considerably under-rated) closer to 470 - 490 hp at the crank (assuming between 15-20% drivetrain loss).
Speaks highly of the untapped potential of the bone stock LS1.
