I was reading somewhere that the engine may be an L99 and not LS3 ? :confused:

Just doesn't really make sense to introduce another V8 variant this close to the end! Also being a 6.2 AFM one @ that :eeew:Quote:

- L99 camshaft is different -- having a little less duration and a little less lift, both of which give the engine a smoother idle.
- L99 has a cam phaser and, to get the additional piston-to-valve clearance required when cam phasing changes, the pistons are different parts having valve reliefs machined into their tops. The reliefs lower the compression ratio to 10.4:1.
- L99 PCV system is different having its oil separators in the valve covers rather than down in the valley like the LS3
Both are 6.2L and the L99 is the AFM variant of the LS3. 400HP is a good start for me! :driving:
Oh yeah. Expect numerous “special” editions with all sorts of fruit to run out leftover parts. Should be some interesting versions.Quote:

I thought LS3 as fitted to the latest HSV's was closer to 460hp (340kw)Quote:

It will be interesting to see if Holden tweak the engine (either one) given that Ford rules the numbers game with 335KW...
I doubt we will see a number that high on a Holden in this update....Quote:

have it on good authority that it will be more than 315 which is what the Chevy SS is rated at, so looks like 325 it will be.
it'll be 307, 317 , 325/7, 334 hmm 334 , they havn't one that one yet, which equals 434hp, so 7 in both , win win and extra lucky ;)
They won't go 334kw so Ford has them by 1 they may go 337kW ????Quote:
