Throttle stops and spacers

[gnicholson]

I have another question for you guys that's tested this on a dyno. Has anyone tested a radius spacer like an hvh under a throttle stop versus throttle stop directly on the manifold? I meant to test this on the engine dyno when I had my engine on it but didnt. my inclination is the throttlestop is like a big four hole spacer and the hvh spacer would give a little more plenum volume and help the air make the turn a little better
