so does this make a huge difference on the mod motors outside of ensuring everything is opening and closing when it should be ??? i know it made some small differences on the old school ohv small and big blocks from my past , not much at all in my flatheads , but no clue here . any noticeable power gains in torque or horsepower ?? just rying to be sure before i go do some things . this car is on a TIGHT BUDGET so i don't wanna do as i have with some others and throw money at it just cause it sounds cool or promising . and since i've not really played with the mods before i'll ask those of you in the know . and yes i tried the search didna come up with anything definitive .
