So i'm contemplating buying a Wieand tunnel ram with dual 600 VS holleys.
Its a 496, bigger valve, mild worked oval head, .630" lift roller cam, that currently has an 850 DP on it.
I've just spent a few hours reading about tunnel rams and carb tuning using the search tool.
I guess I've just always wanted one, but is it worth it? Its just a lake boat that i don't need every inch of power out of, but it seems like they really are a great intake. It seems properly tuned they don't produce any noticeable increases in fuel consumption, but wake the throttle response all over the RPM range.
Next question is, is the 600 VS not enough on a 496, I'm not going to use the 660's but most guys are saying the 750s are better than the 600's. Could the 600's just be jetted bigger? Or is the VS just gonna cancel out the benefit of wicked throttle response while waiting for the vacuum signal?
Sorry its so wordy, I just keep going back and forth...and back and forth again.
