I ran a slanty for years in my '68. It ran very well for a slant, but it would only pull down 16 to 18 mpg on the highway at 75mph and 13 to 14mpg around town.
I had a two bbl, slightly ported head with oversized valves, an RV grind cam, bumped-up compression and Dutra Duals. In fact, the motor was done by Doug Dutra.
Like I say, it ran great, but I always wanted more. I ended up pulling it to put in a 2001 360 Magnum with fuel injection and some other mods. I expect to get way more power and equivelant or better mileage when my foot is out of it.
