New Hemi Swap with Borgeson Steering Box?

Well, the B bodies have way more room for all the components. You guys are expecting WAAAYYY too much out of these aftermarket vendors. The bottom line is there is not enough room to fit a Gen3 Hemi into a stock A body engine compartment. You can use the aftermarket as a start, but expect to modify; dent; cut; etc to fit it in. I realized early on and went with the AlterK set up and haven't looked back. For those who resist an AlterK or Denny'sK, you can get one to fit, but you're going to have a cut up, dented up mess by the time you're through and still probably have rattles and vibrations to boot.

If you want to do a "clean" install of a Gen3 into an A body, include an aftermarket suspension in your budget, right under the cost of the engine itself...

My gen 3 dropped right in on a factory K member pretty easy. I didn't have to modify any of the body to make it fit. I originally planned to use factory manifold of some variety and swap to headers down the road, but figured I'd rather only do the job once and got a set before I put the engine in. They actually dropped in pretty easy and required no mods, but they are a pretty tight fight around the torsion bars. I think the main problem is that tolerances weren't well controlled back in the day and some of the parts have shifted and fatigued over their 40+ year life. One guy will drop an engine right in and the next will have to cut half his front end apart. You never really know until you try it yourself unfortunately.
