Slick 60's

Nice, while you're at it throw a couple of turbos on there and take advantage of that fuel! Your engine is probably as clean inside as your truck is outside.
If E85 goes away, I may end up looking for a tank like yours (and a place to hide it in a Mustang)!

will be a lot easier than topping up the 200ltr tank every now and then

WHAT!
Some IDIOT decided a 50ltr usable tank was enough for my slick with a 351c.... Needless to say the I now have many new 'service station' friends because I am there so bl00dy often!
