Hey guys. I have been a member for a few months and i wanted to get some input from some of you guys. I have the doggish lo5 motor and i was wondering if you could give me any specific numbers on what i could gain in hp and torque with the basic bolt on mods. I`m also looking for a set of 062 vortec heads. I just got the truck running right and even though it has tons of low end i don`t really care for the loss of power on top. I`m thinking of the vortec heads new and larger throttle body with a set of gibson headers and custom exhaust. I was also wondering if a dual 3" exhaust would actually hurt power. I have heard it argued both ways where too big exhaust is bad just like too small exhaust is bad.Any input would be appreciated thanks.
