these engines don't need more torque they are little torque monsters for their size. what you need is to move your power UP the rpm range. If it wont run up to 4000 before you shift then when you grab that higher gear the rpm will drop to the very bottom of that torque curve and struggle. the factory expected you to shift at 3600 and with a stock carb, cam and exhaust most wont rev past 4500.
I love my cam. I have F150's in the back and they are real soft til they get way down there. which makes for some insane flex on the trail
