Horsepower estimate

anyone have a ballpark estimate of the HP of a 440(10.5 to 1) with the Indy Sr Top End kit with a 509 cam and a 750 carb?

thanks

Well stock you can figure around 390hp before any changes if you compression estimate is accurate. Given the cam and head improvements I would guess somewhere between 425 to 450 to be on the safe side and depending on if there have been any other changes made that you didn't mention. If you figure a max of 450hp you should be fairly close.

little better carb 850 and 557 solid 500hp easy

thanks!
