I cant seem to find the answer to this so any help would be appreciated. I have a 1997 Sierra SLE Z71 w/5.7 no mods. What is the stock horsepower and ft. lbs torque. If anyone knows I would like to know. Thanks.

The h.p. for your truck is 245! Don't know what the torque is.

Good Luck!

GM rates it at 255hp.

I appreciate it. Dont know if it matters but it is an extended cab. Anyone who knows the ft. lbs of torque it would be greatly appreciated

330 ft.lbs of torque is what I have found.

Thanks. Im just curios because I want to make some performance mods. and wanted to know that info. Thanks again.

What kind of mods are you planning on doing to your truck?

Im not sure. Id like to get a better 0-60 speed and more speed off the start. I was going to put a throttle body spacer and dual exhaust. Any suggestions would be helpful. Thanks
