Remember you have to run slicks.
Steve is right, Drag Week rules require either drag slicks or DOT approved slicks and NHRA rules require a driveshaft loop if running slicks, so next on the To-Do list was installing a drive shaft loop. The next best thing to having a car hoist is having a friend with a hoist, and my racing buddy Brad just happens to have a hoist in his garage. I had helped him earlier this year on the new race engine install and updates on his race car so he was happy to help with driveshaft loop install. It all went pretty easy. I used a Lakewood universal driveshaft loop kit I had sitting around. The upright portion of the support legs usually need to be shortened on all the Ford installs I've done in the past and I had previously cut off about 2" of these with a chop saw. We put the car in the air and did a quick visual on a possible place for the support legs to position on the floor pan. There was a spot within the required 6" of the front u-joint where the floor had some embossed ribs that the supports fit perfectly within, so the hope was that position might work. Next we brought the car back down and unbolted the seats. We left the seats in the car, but just tipped back. We pulled up the carpet in the front. These Lincolns have a ton of wiring running on the floor from the front of the car to the back as well as side to side, so the next concern was if the chosen spot would have issues with wiring interference where the holes would need to be drilled to mount the loop support. I got lucky here as the wiring ran close, but not over where the holes needed to be. I also got lucky as there weren't any floor or seat braces in the way. From below Brad drilled one mounting hole at a time using the driveshaft loop supports as the template and with me above I fed the bolts down through the floor and support. With everything in place it was just a case of tightening the bolts and putting the carpet and seats back in place. I know this is pretty basic for most of the people here on the forum, but it may help someone thinking of getting their car race ready, it's not too involved of a project. Here's a couple pictures:
In the case of my '78 Lincoln ( and most older cars ) there was plenty of room around the exhaust and driveshaft tunnel which helped. Just for comparison, here are a couple pictures I posted on the forum a few years back when I was getting my '96 Lincoln MK8 ready for the dragstrip. It was a lot tighter and the exhaust ran right under the driveshaft. My friend BradFord had to custom fabricate a driveshaft loop from scratch that would fit.
The loop above is what BradFord made, the loop below is a universal driveshaft loop for a late model Mustang.
