280, to 300. NEW ANSWER: Straight out of the book. Advertised Horsepower is-175 HP @ 3600 RPMs. That engine STOCK didn't have HORSEPOWER it had torque
The 400 Chevy small block motor should have approximately 390 horse power. It should have 427 foot pounds of torque.
stock they are 160hp and 400 ft.lbs torque.
how much horespower does a kfx 400 have how much horespower does a kfx 400 have

Factory stock, the 400 cu. in.
400 billions.
70 ft/lbs.
just about any Chevy trans, a TH350 or a TH400 are the most common and will both fit. as far as engines and transmissions with Chevy's there just about all interchangeable without to much messing around. only difference with a TH350 to a TH400 is that a 400 will take higher horsepower/torque. but for most stock applications a TH350 will be fine , oh and the TH400's are slightly longer to.
