Can't believe the advances in engine development nowadays. Car & Driver has a writeup on a small 4 door Mercedes for public consumption (not a race car) with an engine that puts out 355HP and 332Ft/Lbs of torque. Not amazing numbers by today's standards except for this---the engine is a tiny 4-banger that's 122 cu.in. (2 liter) and weighs 326 pounds. The thing turns the 1/4 mile in 13.3 seconds. Also was a new Land/Range Rover with a 305 cu.in. engine putting out 510HP, 108 MPH in the 1/4 mile, 13 seconds. By contrast, the "hot rod" boys on another site say my old 7.3 IDI turns a blazing 66 MPH and 20 seconds in the 1/4 mile. With those stats as a starting point, unlike some of them, I just don't think I'll be spending a couple thousand on a hi performance IP or a torque cam.
