what are the h.p. gains on an otherwise stock 94-95 mustang if you were to change the roller rockers to a 1.7 ratio??

who makes the best / worst 1.7RR?? (opinion)

specs on valve lift??

spend your money elsewhere on a stock car...gains would be minimal.
Look into gears

Yep!

Buy gears, pulleys or CAI. They would do more than the 1.7 RR's on your motor.

thanks guys but dont need help building h.p. for my car..
it was a conversation i had with someone on their car about changing the valve lift, h.p., specs..with 1.7RR on a stock motor..he has already done the swap and swears the car is faster and way more responsive..im just trying to see if he really has gained anything..

is that a guesstimate 0-2 h.p.??

Nope, either 5.0 Mustang or MM&FF did a dyno test for 1.7 rockers and the gain was exactly that over 1.6s - very little change.

does this also hold true if you were to swap the heads out to gt40 irons as well?
