    Default holley throttlebody

    HI all, fairly new to the forum here, was just wondering if anyone on here with an older TBI 305 or 350 (5.0 or 5.7) is running an after market holley performacne throttle body, im thinking about putting one on my truck, just in serch of a bit more power and wondering if it was worth it, ive already got an exhaust and custom intake setup, if anyine could let me know it would be appreciated

    On that motor you would really benefit from adding a throttle body spacer as well...

    lol, my 95 has the 305, but the 5-speed behind it, so I never notice the low end problem. I always noticed the top end lacking tho. My 2000 Sierra is awesome tho. Lots of low end and top end.
