I know that feeling.... getting the itch myself. Haven't built one for quite a while.

Thinking (if I do a build) that I'll reskin my 2004 Silverado and then do a build on the engine. Reprogram the shift points on the transmission. On this truck I think a 350 hp/400 ft-lb engine ought to make it scoot without doing too much damage on mileage. On the Gen III it is easy to go in thinking restraint and end up with a 450 hp engine that gets about 10 mpg...
