Interesting V6 guide
Found this info on another forum and thought I'd share. 
M112 E26
The E26 is a 2.6 L (2597 cc) version. Bore is 89.9 mm and stroke is 68.2 mm. Output is 170 hp ECE (125 kW) at 5500 rpm with 240 Nm (177 ft.lbf) of torque at 4500 rpm.
Applications:
1998–2005 C240
1998–2004 CLK240
1998–2004 E240
M112 E32
The E32 is a 3.2 L (3199 cc) version. Bore remains at 89.9 mm but the engine is stroked to 84 mm. Output is 218 hp ECE (160 kW) to 224 hp ECE (165 kW) at 5700 rpm with 315 Nm (232 ft.lbf) of torque at 3000-4800 rpm. It has fracture-split forged steel connecting rods.
Applications:
1998–2004 C320
1998–2004 E320

M112 E32 AMG
The E32 AMG is a special version of the 3.2 L (3199 cc) E32, fitted with a helical twin-screw supercharger and water-to-air intercooler. The supercharger was developed in conjunction with IHI and features Teflon-coated rotors producing overall boost of 14.5 psi (1 bar). Output is 354 hp ECE (260 kW) at 6100 rpm with 332 ft.lbf (450 Nm) of torque at 3000-4600 rpm.
Applications:
2001–2003 C32 AMG
2001–2003 SLK32 AMG
2005–2006 Chrysler Crossfire SRT-6
M112 E37
The E37 is a 3.7 L (3724 cc) version. It retains the 84 mm stroke of the E320 but is bored to 97 mm. Output is 235 hp ECE (173 kW) to 245 ECE (180 kW) at 5750 rpm with 254 ft.lbf (344 Nm) of torque at 3000-4500 rpm.
Applications:
2003–2005 ML350
2003–2006 S350
2003-2006 SL350
M272 E25
The E25 is a 2.5 L (2496 cc) version. Bore dimension is 88 mm and stroke is 68.4 mm. Output is 204 PS (201 hp/150 kW) at 6100 rpm with 181 ft·lbf (245 N·m) of torque at 2900-5500 rpm.
Applications:
2004–present C230
2005–2009 E230
2008–present CLC230
M272 E30
The E30 is a 3.0 L (2996 cc) version. Bore is 88 mm and stroke is up to 82 mm. Output is 231 PS (228 hp/170 kW) at 6000 rpm with 221 ft·lbf (300 N·m) of torque at 2500-5000 rpm.
Applications:

M272 E35
The E35 is a 3.5 L (3498 cc) version. Bore dimension is 92.6 mm and stroke is 86 mm. Output is 272 PS (268 hp/200 kW) at 6000 rpm with 258 ft·lbf (350 N·m) of torque at 3500 rpm. A direct injected variant debuted in 2006 under the name Stratified-Charged Gasoline Injection (CGI). First fitted to the CLS350 CGI, it produces 292 PS (288 hp/215 kW) and 269 ft·lbf (365 N·m) of torque while lowering fuel consumption. In 2008, the non-CGI engine was uprated to 316 PS (232 kW) at 6500 rpm and 265 ft·lbf (360 N·m) of torque at 4900 rpm. This was achieved by raising the rev-limit to 7200 rpm, increasing the compression ratio and other modifications to the valvetrain.

2006 C230 6 speed
The M272 really comes alive after 3k RPM. I find myself living over the 4K range with my 06 more then i did with most other cars i owned, the chart makes it clear why

If the bore is the same, then replacing the crank (and possibly arms) would change a E25 into an E30? Does the E30 share the dual runner manifold? I understand that there would need to be some ECU tweaking, but that sounds really interesting.
