I got a old hemmings muscle machine magazine and it says that a 429 for a 71 torino would put out 370 horsepower @ 5,400 rpm's and 450 torque @3,400 rpm's.Then there is another one that is rated a 360 but don't know much about that one, but it is in another HMMM magazine just different month.But does not give all the information like I have for the first one.It says that it is a four barrel the one that is rated at 370 hp. I didn't know if you wanted the rpm's I just wrote it like it is in the book.
