hp is hard to tell from ci.... what kind of heads and cam and exaust and compression and carb and intake and such are you running?? motors ussually follow 1ft-lbs of tourque per ci.... but even that changes a good bit depending on the rest of the set up... the block and such dont really make much hp... mostly the block tells more about the tourque of a motor... hp is all in the top end

I have a completely stock all original 1965 Plymouth Fury III.

With the stock motor (this is a Dodge block though) it puts out 260 hp @ 4400 rpm... It has a 2 barrel carb, 9.2 compression and a 3.375 stroke.

It's supposed to put out 270, but I'm sure this is because the car once sat for 20 years and all I did to it was replace a bent pushrod and give it an oil change after it ran about 50 miles. I bet just getting it hot tanked and balanced would give it that 10 hp back.

A four barrel carb jumps it quite a bit, the difference between the 2 and 4 barrel stock motors on my car is 45 hp, but I don't know if the 4 barrel has a different intake manf. or anything...

If you're just wondering whether you can get good horsepower out of it... Of course you can...

In my opinion any V8 thats a 327 or up is worth its metal... But if you want to just eat everyone else up, it's all about the big blocks buddy...
