Another small block stroker combo to ponder.

I probably have gaskets and bearings and I know I have a mellings Hi Volume pump. I will probably have to buy a timing chain. Im really down to a couple of cars I could use this in. I have a 1992 one ton 4x4 with 4.10 gears that has almost 300,000 miles in it but I hate to put it in that because its not a real pleasure to drive and besides the original motor is still going. I have a 1939 Plymouth coupe that I am building for my Dad, its already got a stock 73 cast crank 340 to go in it and my dads 83 so I'm not sure he needs a 408.What does it take to put the fuel injection in an older car? I do have a 1966 Plymouth Belvedere 4 door I could put it in.
