what's up olds nation. can someone tell me the horsepower on 1973 455 98.

 

The chart indicates '69 but doesn't say "to '76". You can read the data from the year 1969 and it will generally be the same for a 455 up until '76 for the same engine/carb/car application. At any rate, those are just advertised ratings anyway, I wouldn't put much value in them.

^^^ hmmmmm according to that chart, my enigne doesn't exsist

 

This is an example of some of the things that hopefully Joe will be able to correct in the future. We all know that information from the internet is usually not lacking but often incorrect or incomplete.

 

according to the info I have the 98 was RATED 340hp (254kw) --that is same from 71 through 76
