And I while I am in there should replace the automatic transmission with a 6 speed manual. Then I will need a Ford 9 inch rear end to replace the fragile stock 8 inch rear end on the car now. And while I am in there I might as well replace the rear brakes with discs and upgrade the suspension. The front brakes will need to be beefed up to compensate for the bigger rear brakes and that suspension needs to be all replaced. I might as will go to electric power steering to clean up the engine compartment, and then the instruments panel will need to be replaced and while I am doing that I should replace the dash and then replace the cloth seats with leather. That won't cost more than 30 grand and take a couple of years.
Nope, I just need a new engine to replace my current engine. I will go from 115 hp to 290 or more for well under 3 grand if I do it right. I did the math and if I continue to drive it about 12,000 miles per year. If the new engine goes 300,000 miles I will 82. I figure by the year 2036 I will have had to convert it to run on hydrogen. The car will be 50 years old!
