Advice for Noob with Slant 6 Barracuda

Do you guys care about gas mileage or do you just want it to go faster?

You can build slant sixes for decent power but it costs $$$.

If all you care about is power then you need a V8 in there.

If you want some more power while keeping your mileage, 2bbl super six is the way to go.

Either way a slant 6 is a slant 6 and you aren't going to make it as fast as the slowest new car without putting some work into it.
