Need help with a 90 model 454

[Uzaree]

I have a 454 motor out of a 90 model SS chevy truck and I've been searching for the factory horsepower rating of this. I'm wanting to run it on propane and I need to get the correct mixer for the horsepower. Thanks for any help.

255 hp @ 4000 and 405 ft-lbs @ 2400 rpm.
