The car will see 75-85% highway use as we live about 30 miles from work and I29 is the route to work. Would the 195s eat more gas than the stock 205 size thats suppose to be on it?Its at 113 miles from when I picked it up with a full tank and seems to be an 1/8 above have tank So my guess is currently around 14mpg. Pretty sure carb needs a rebuild and possible bad gas that was aparent after I got it home. Ran pretty good down the interstate. Is there a diff between car and truck 4bbl kickdown linkage? I have a few truck ones
