The general idea is an LS based V6, sharing 75% of its parts with the V8. Cast iron block engines would weigh 370 lb, and all aluminum versions come in under 300 lb.
There'd be a 3.6L with 240 hp, and a 4.6L (282 cu.in) with 280-300 hp. They'd have sinter forged powdered metal connecting rods, forged crankshaft, and hypereutectic pistons. I would like to see high pressure die cast pistons (an ohv V6 version of the Toyota 2JZ inline 6). They'd also be available with AFM, piston oil squirters, VVT, 3 valve/cylinder, DI, etc as the V8 evolves.
As a consequence, the 3500, 3900, 4.3L and 4800 V8 would die. The 5300 would have to make 340 hp, and the 6200 makes 412 hp. Thus, the only ohv engines in gm's lineup would be a 3600/4600/5300/6200/7000.
The 3600/4500 would also inherit the small block's enormous aftermarket; the common parts would further reduce cost for both engines. A simple cam and headers would take the 4600 to 400+ hp. They'd be turbo-proofed for ~800 hp on stock internals. An LSX version with 14 bolt heads and 380 cfm intake ports would handle 1800+ bhp, and be ridiculously cheap. The V8 and V6 share the same CNC programs, cam profiles, and fuel/spark maps.
Who could argue with a $4000 crate engine, with all aluminum construction, 300 lb fully dressed, 6600 rpm redline, 400+ hp with cam and headers, and ready for turbo or 150 shot of nitrous? the 4600 would revive the spirit of the Stage II Buick, the most hallowed V6 in history, and take it further.
