Three years ago I helped a cohort put one in a '68 Bronco (converted to 2 wheel drive with a set of late model mustang struts)...Had a local Ford mod motor whiz do all the wiring.... We used a Milodon pan and a remote oil filter mount with -10 lines. For the exhaust, we had a local laser cut company cut out some flanges and built a set of long tube headers, 1 5/8" with a 3" collector. Been awhile, but if my (feeble) memory serves me correctly we used the stock steering box, relocated the column slightly, and a double universal joint (from Speedway).

Anyway, it worked out very well, other then burning up a couple of AOD trannies till he had one built. Last year he had the same shop that did the wiring add a Procharger to it, and is now doing some research on converting to the DOHC heads, or maybe the 3 valve. It's a bullet now, but I guess there's really no such thing as too much horsepower.

Should be a bit easier now, there's a lot more parts available for the engine and the swap has been done by enough folks that there's some good information out on the "how to" part of it... Sometime this winter I'll be getting back on a guy's '67 Mustang that is getting a full chassis and a supercharged 5.3 with a Tremec 5 speed....

Sounds like you're getting close on yours! Sure would be a shame to give up on it now and do some feeble I6.... No comparison in performance, operating efficiency, and good old eye candy appeal.......
