I searched on Google but couldn't find what I needed. I used to have a link with the numbers, but I must have lost it. Anyway, I have two trucks and was wondering what the factory hp and torque ratings are on each, I'm trying to justify an engine swap. 1989 C1500 with a 5.7 - - - HP? Torque? 1995 C1500 with a 4.3 - - - HP? Torque?
