650hp 550ft lbs easy!!!!Any plans for dyno #'s before delivery to T-Fab?
That seems to be the concensus. We've built a few of these for drag cars and hit low 700's and mid 500's. The configuration is a bit different, lower rod ratio, much different cam characteristics, much more bowl work with less port enlargement, we're trying to get the torque over 600 for 2000rpm usable. We may have to dial it back so the rig doesn't flip on its lid every time he throttles it650hp 550ft lbs easy!!!!
I would run the L92 truck intake over the L76 car. It should give better low end. The biggest thing with LSx's is getting the right cam. Not sure if it will be that high torque in that low of the rpm band it would be nice to know what it makes.That seems to be the concensus.

Have you found a cam for it yet? I am look at adding L92 heads and intake on my 6.0L and was wanting a have torque low power band cam. Most i seen make peak at above 6000!I've assembled more than thirty LS engines. I have dyno numbers on more than ten of them. The last engine I built with similar components made 601hp and 544tq. I'm hoping to bring the torque up and flatten the curve a bit, but even if it makes the same as the last engine it'll hand an ls7 its ass.
The L92 heads are a bit large for a 366 unless you are trying to make peak above 6000rpm. Your port velocity will fall and drop your torque. Look into ported 243 castings instead. The cam stuff for L92's is non-existent. The store bought profiles are all for cathedral port heads.Have you found a cam for it yet?

The L76 6.0L (vortec max) use the L92 heads and intake just with a lower compression ratio.

I thought the VVT was used to help with the larger heads?I think GM went a bit big on that engine. The LS2 heads have better velocity on <380" engines and make better torque...especially below 6000rpm. The trick would be a VVT 6.2 with LS2 heads and a cam with a bit more lift. It might be worth checking if anybody has a VVT loom available and git ya some of that technology.
L92'sWhat heads are you using? (did I miss it?) Can't wait to see how this turns out:smokin:
