I'm looking into getting new rocker arms (type not sure on). I was wondering what ratio to go with being I have a MTI TI cam . Also from what I understand different ratio rocker arms allow a cam to have more lift ? What gain would I receive from such a mod ?

whats the T1 cam lift. to calculate lift with different rocker ratios take you lift (.564 for an example) and divide that number by 1.7 which is the stock rocker ratio. for my example that gives a .332 rounded up to the nearest thousands. then multiply that number by whatever rocker size you want to try out. 1.8 = 597.

for most cams the 1.7 ration rockers are fine and prefered as a higher one will send the lift through the roof. keep in mind the springs your running too cuz often times you can exceed the max spring rating by going with a higher ratio.
