We are getting old, the LS is the new GM small block. How many old GM 350 blocks are left? The GM 454 blocks are gold around here. The cost of aftermarket blocks will make the LS more popular before it is over we will all probably run a LS motor at some point. Think in the 70's electronic ignition and disc brakes, 80's fuel injection that would never last. Change scares people, but is sometimes for the best. Just my 2 cents!
