Runners in a Tpi
I read this runners add around 15 to 20 horse power. Also how will they work on a stock intake and straight pipes on a 87 vette ? thanks

They bolt on pretty easy to your car.
Maybe more like 10hp if that is the only component you change. Biggest improvement is that your power band would extend 200-500 rpm past 4,500rpm. I would stay away from Edlebrock, don't believe they flow much more air than stock. Plus I think they look crappy. Those siameesed runners are good. TPIS large tube runners are good too but more expensive.

Stock runners are very restrictive so changing that will help your 350. Base manifold is also restrictive. What are you long term goals for car? Just asking since people usually do more than just larger runners and there are lots of intake options/upgrade paths you can take.
