Hello all,

Can anyone sum up the differences between both available engines ?
As I know during the model 1976 model year they changed from the 455 to the 403 engine.
What is the difference in power, economy, reliability, maintenance ?
Should I choose my GMC by the engine in it, or are they about equal in general ?

Thank you all,
Dominik
