Fuel Injection add on??

My brother did the Fast 2.0 on his 520 ci big block using the stock distributor. I simply locked it out and phased the rotor and trigger wheel then synced it with the 2.0 system. I read a thread on moparts or FABO it was not straight forward but took less than a day to complete. I and most everyone recommends an in tank fuel pump he built his own sump and it doesnt uncover until an 1/8th tank or less.
The MSD system is what I am looking at for a mild small block due to its simplisity and timing control. The 2.0 is awsome but more than needed for a less radical build.
