What mileage does your slant six powered ride get?

170's are the greatest little motors for a driver.With a 4 speed behind it (not an overdrive one) they are lots of fun to drive. That little short stroke motor is very responsive when you set it up with the right trans and rear.

I'll agree with that. I had a souped up 170 behind a O/D manual in a 64 Barracuda. Ran great, unbelievable mpg and good power.
