I wasn't sure where to put this. I think this is more than just a rumour. It is to be called LV3. It will definitely have aluminum heads, and likely cast iron block. I'd love to see a 60° V, but it will likely be 90° with a balance shaft. I'm guessing it will have 280+ hp and 275 lb-ft stock. It has the potential to make 400+ bhp n/a and rev to 7500 rpm with the right combo. It will have direct injection, coil near plug, variable valve timing, and light weight components. It will have a raised cam (56mm diameter) and bed plate (instead of individual main caps). The high value V6 had forged cranks, and I expect the LV3 to have it as well. It's a seriously stout engine!
I quickly designed a series III 'Stage II' head yesterday. I can machine it from billet, and possibly cast and sell at a very reasonable price for a limited niche. However, I'm disliking the Buick motor more and more as I learn about it. I never liked the head bolt pattern, and its short comings, and how it negatively impacts the exhaust port. I want to duplicate the Stage II exhaust, and I'm having a challenge getting blue prints. My head would require custom heads, rockers, rocker covers and headers...it gets expensive quick. An LSX based V6 would be cheaper by far, and benefit from decades of design evolution - it's the way I'd want a V6. I believe that the LV3 will satisfy people up to 800 hp and put GN aftermarket heads out of business - GM is leaving very little on the table with the Gen V.
Who would pick up a $4000 V6 crate engine if it were like this?
