SLP runners on the dyno?
Anyone have any dyno results after they installed a set of aftermarket runners such as the SLP's? I am curious on how they will respond on a bolt on 350. Otherwise stock internals engine.

Re: SLP runners on the dyno?
Runners by themselves no other mods? 10hp at most. Port matched, slightly more. The runners aren't the biggest restriction in the TPI system. Its the base. The gains show up more in the top end than all around.
