(A fully built & perfectly balanced engine would be able to combat this more effectively if it were forced to have a smaller HB but it doesn't guarantee anything.)


The 4.6 is easily a 200k mile engine but the less control the HB has on it the sooner it's going to give out. So instead of having 200k miles of fun, you could have only 120k +/- what ever the car gods see fit.

Think of a smaller HB as a woodpecker.... It just picks away at a tree little by little and eventually it burro's it hole. The smaller HB pecks away allowing more TV and eventually it's going to give out.
