Since this is the area for "benchracing and daydreaming" I thought I'd post this....a local engine shop suggested that a 540 cubic inch engine would be "just the ticket" for a heavy vehicle like the K5. Supposedly, they have GOBS of torque and would make the truck "feel" a lot lighter and quicker. How is an engine like this created? I heard that it's all "custom" parts since the factory never did anything that size. Does it use a 454 Block as the basis for the buildup? I know there are some serious engine "gurus" around here, so I thought I'd just throw this fantasy out there and see what people think. Forget about the $$$$ or practicality aspects (who wants to consider such bothersome topics? /forums/images/icons/laugh.gif) I just want to hear people's opinion on the "Cool Factor" of stuffing such a monster motor in a K5. I always thought the idea of a motor that could produce 500 Lb/Ft of torque from 1000 RPM to redline would be awesome.....and I have a feeling that this is the motor that could ACTUALLY do it!!!
