How Much Of A Performance Gain Would I Get By Going To 1.7 Rr Compared To My 1.6 Rr, Or Just Doing The Intake Like I've Seen Alot Of People Going To.. Is It Doable With Out Having Flycut Pistons? I Have The Twisted Wedge Heads, And The Tfs Stage One Cam... Are There Any Dynoes For This Change? Thanks Guys
