If you were to build up a GenIII truck motor from scratch with these goals in mind...

This is what I would do.. I would get a 2001 6 litre iron block and LQ4 heads .. The bore is 4" on the 6 litre and that is a real nice size piston to stay with.. I would then go with a 4 1/8 to 4 1/4 inch crank.. This would give you say 415 to 427 CID of motor( didn`t calculate it but close).. I would then have the heads ported and a little larger valve installed.. To keep up my low end torque and still make good power, I would then run a B1 cam..221/.221 .560/.560 on a .114 lsa.. This cam will run and Idle real smooth in a stroker motor.. This motor would probably make 460 to 470 RWHP and be real reliable..I would also put in some good forged heavy duty flat top pistons and have the heads decked to bring compression upto 10.8 to 1 or so.. I would then put a 150 TNT wet shot ontop of that and HANG on for some TRUCKIN FUN!!

Its safe to offset grind. Still, new rods and custom pistons would make some run the other way. Although that would be the time to upgrade <img src="gr_stretch.gif" border="0">
What your doing is making the crankshaft pin smaller but it is not ground on the pin center line, its ground offset, you can also slightly destroke engines that way. Lets say your crank rod pin size is 2.1" on a LS1, you can take off the shelf rods for a 2.0" small journal old school SBC 327 in almost any length you want, and use corresponding bearings to use with the offset crank. The newest Hot Rod Magazine went into stroking engines pretty good, you should read it, I would but I already know everything, lol j/k. I think you can only add .080" from offset grinding? I don't think it will add any magic torque numbers myself.
