I am currently building a .060 over 235 for our '60 Apache project. This truck will be my wife's. I want her to have a reliable power plant, no starting or flooding issues. I believe the EFI will greatly increase the overall drivability of her Truck.

I am adding the Holley Sniper to this build. I expect some gains, I have changed the cam(Melling CCS1), done some head work, milled .040, added larger intake valves (1.94"). All this is to aid in powering AC, power steering, power brakes.

The Truck will also have a Lugnutz prepped T5 overdrive with a 3.90 rear gear. I am anticipating some decent milage gains as well.

Edit: Just a few things to consider about using an EFI. The fuel system requires a return line and high pressure pump. The Holley system uses an internal pressure regulator, the Aces I have used on another project required an external regulator. The exhaust is another subject, the system needs an O2 sensor within so many inches of the flange. The stock heat riser needs to be closed or eliminated. Unlike a Carburetor and EFI does not require the manifold to heated, the EFI supplies atomized fuel from the onset.

This is a very "Doable" project for an early inline 6, I think it will have some great benefits once things are all worked out. DO YOUR HOMEWORK...
