roller rockers

morning guys, any noticeable performance gain by installing 1.7"s on a stock( for now)SD with HO upper, throttle body, true duels stang shorties?? and how about a 65mm throttle body?? would the 65 be to much ?
 Thanks in advance

The 1.7 rockers are a good addition as you will notice some more pull higher up where the SO motor needs it.  As far as the throttle body I'd go with a 60MM unit from an HO motor.  The 65 MM is not necessary for the combo you have.
