hey-- i'm looking to buy a 77-79 (i think) f-150. it is a long wheelbase, but i need to figure out some stuff before i put down the $$$. first, it has a granny 4 spd. so is this more likely a np-435, 420, 465??? the motor is a 400 bb, but it's almost shot, so will a 300 six bolt up or will i need a new bellhousing? i think it has a married 205 t-case, and i am interested in doing the 205 and 203 dual t-case swap, but which 203 will i need?
thanks

Most likely it's and NP435 could be a T-18 but doubt it. The SM420/465 were only used in chevy's. A 300 won't bolt up to either the motor mounts or bellhousing. You'll need a married 203 from any Ford to get the right spline input...unless you want to swap it.

I have a 78 F150. It has a 435/205 AND the 300 ci six. All you should need to convert it over is a new bellhousing, flywheel clutch assy and the motor.
