Listed from Ford for my 76 Gran Torino;
351M 152HP @ 3800 RPM, with 274 Torque @ 1000 RPM (Wonder if 1000RPM is a typo)
400 180HP @ 3800 RPM, with 336 Torque @ 1800 RPM
Just for comparisons; also listed in book
351W 154HP @ 3400 RPM, with 286 Torque @ 1800 RPM.
460 202HP @ 3800 RPM, with 352 Torque @ 1600 RPM

It's good to remember that those numbers are not close to what a RV build can do to the 400- around 250-300hp and over 400ft lbs of the good stuff. The truck 400 motor- started in '77 and was under 170 hp- detuned and decompressed for the new fuel.

I agree; tons of potential as I hope to find out.
In my 76 Torino (Starsky and Hutch replica) is a 351M, the restoration facilities are rebuilding the motor as 400ci, Mild cam (Comp 270H), bager pistons (9.5:1), new carb, intake, header, dual exhuast and so on. Must admit I don't know much about motors but am learning quickly from this formum. They indicated they expect 400+ torque and about 300hp. They will know exactly once its finished and dynoed.

most builds that I have seen by engine shops are stock
builds that really limit the power back down to the crappy numbers that ford put out when they decompressed/detuned these motors. It blows me away that they would do this.
