No, but I have done a few vehicles with that '88 Ford truck pump. (A '69 Corvette and a '50 Ford truck). It says to use a primary "kicker" pump with it, but I did not in either of those and both are still going 10+ years later. I prefer the intank pumps and if I did another it would also use that S-10 Blazer tank too. I would have to say that after seeing some wrecks with in cab tanks, I would prefer to get the tank outside.
The only real difference in a 350 and 305 setup is injectors and knock sensor. You may get away with the 305 injectors if you jack the pressure and/or don't rev it high. Another lesson I have learened in the last year is injectors. The GM Multec injectors do not like ethenol fuel. There is a guy in Atlanta that sells rebuilt Bosch injectors that fit that use stainless pintles and should last a long time with todays fuels. Before the carburetor guys jump on the bandwagon, remember that some Q-Jet floats and especially older accelerator pumps do not ethenol fuel either. Fuel quality and chemestry is a real problem whether you are carbed or injected.
