I repowered earlier this year. The old motor was a 5.7 4 barrel with a mechanical fuel pump. I reused all my accessories (same carb). The new motor required an electric fuel pump. I CAN'T GET OVER HOW EASILY IT STARTS UP NOW. I started it up this past weekend (too rough to fish) after it had been sitting for about 7 weeks. I turned the key on and let the fuel pump pressurize (about 2 seconds) and then turn the key. It starts just like any modern fi engine. Anybody that has engines with mechanical fuel pumps (that require cranking to pump fuel) I believe an electric fuel pump upgrade would make starts easier.
