289 hp numbers
Hi I know that these will all be estimates but I would greatly apreciate any honest answers!! I was wondering what type of horsepower numbers I might be making with this motor in my mustang. I have a 289 it is bored 30 over, mild cam, edelbrock intake manifold, carter 625cfm carb and long tube headers with 2.5 flowmaster exhaust all the way back. Thanks for your time!! -John

I had a '71 Torino with a two barrel carbed 289 that was factory rated at 190 HP if memory serves me correctly. A lot depends on the cam you installed and the compression ratio, etc. but I would think you might be at 250 at the flywheel.

160-180 RWHP depending on trans type.

Our 65 coupe with a 289, mild cam, performer intake and some mild head work makes 178 RWHP on a chassis dyno through a toploader and an 8 inch, runs on 87 octane.

But those are quick horses, not slow power horses.

Quick horses vs power horses??
What 2 motors are we comparing?
The 289 4v vs the 289 HIPO?
Can you quantify what you mean by the difference between slow power horses and quick horses?
Not being a smart ****, I just don't understand.
