the 4valve is a fun motor to play with at the strip or on the street. A convertible is actually pretty easy to build for the strip from a chassis perspective, as you have such easy access to everything. I have seen a couple of convertibles made into removable hardtops out on the west coast, but have never seen one on the Atlantic side. You can find a rusty coupe, cut the top off, use parts from the convertible top (latches and seals), and create the removable top. Take it off for the strip or a nice cruise night. There are tons of options for the drag strip. If you go with one of the newer automatic transmissions, you can use a programmable paddle shifter like the Shrifter from Twist Machine. That gives you both hands to wrangle the beast down the track. There are plenty of bare-bones interior options for the drag strip as well. The Lincoln four valve comes with the Teksid block, but a cast crank. There are plenty of new and used forged cranks out there and you have your choice of compression ratios as well. Head/cam/intake choices are plenty, so read a lot and build something that suites you. There is a decent article on here that will tell you about some of the bottom end options for the four valve.
