Mi risulta che LS1 camaro abbbia 305 cv non 288,i due motori sono sostanzialmente identici a parte suppongo dei chip diversi e qualche dettaglio.in questo forum di cui post il link i ragazzi rullate alla mano parlano di 320 rwhp (cioe' alla ruota)

estraggo un post per semplicita'
"Corvette vs F-body LS1:
-exact same heads
-exact same block
-exact same crank/rods/pistons
-exact same intake manifold
-slightly different cam specs (negligible)
-different shaped oil pan
-different serpentine beltpulley layout


Corvette LS1vs LS6:
-different head castings (LS6 flow slightly better stock)
-different intake manifolds prior to 2001 Corvettes. All 2001 and newer Corvettes and F-body LS1s have the LS6 intake.
-different cam specs (02-03 LS6 cam is much better than 01 or regular C5)
-different PCV system
-slightly different block internals (crankcase port windows larger on LS6)
-same crank and rods, I believe pistons are a bit different

Basically the pulley layout and the oil panshape. Corvettes have a flat oil panwith "wings" on the side, which don't really fit in any other vehicles very well.

There are quite a few bolt-on LS1s running mid-high 11s with no internal engine modifications, all in the 3100-3200 lb range."

Hope it helps all this info was found in " f-body ls1 vs. corvette ls1vs. ls6" July 17th 2003.
