You can do it for fun, you can do it to be different, but don't do it to be fast. You could bolt twin turbos onto one of our L6s and they'd still run 18 in the quarter :-)

I had a buddy with a 65 Chevy Van that built the 6 in it. The only scary part was it'd get up to about 240F and he'd open the engine cover (between the seats!) to help cool it as we drove. I was ready at any time for an instant scalding - not something I'd do now!

Which brings me to my point: don't wreck your driveability in pursuit of speed, because you won't get speed, so keep the driveability. It can still look cool though!
