I don't have a service lift. The drivers side was easy once the steering shaft and valve cover were removed, it dropped in from the top. How high up do I need the front end to wiggle that son of a gun into the passenger side? Yes, alternator and starter are out.

It's up on about 18 inch high, (perhaps a bit more) jack stands under the front cross member and no luck. The drive on ramps weren't high enough. Do I need it to be scraping the rear bumper?

 

I had my car up HIGH (enough such that I could comfortably lay under the car and get the header almost vertical under it) and then I had the engine jacked up as high as I could get it without crushing fuel lines etc. for "ease" of installation. There's no way you'll be able to get it high enough on ramps, you need a floor jack and some pretty tall jack-stands.
