Hello, I am replacing my stock 400m with a built up 429 PI. Will I need to replace my radiator or other cooling devices to accomadate the 429?

you shouldn't have to make sure you have good flow and a shroud use a 460 heavyduty clutch fan

The truck year is 1978, F-250 Ranger XLT 4X4, and I am going to put in a rebuilt C6 transmission.

ok. cool, you dont have to buy a flywheel and if your using hooker headers you only have a slight mods .use a rear sump pan and p/up and what are you doing for motor mounts?

not sure yet, I don't think that I can use the ones from the 400m, so I will probably buy some. or have some made., what did you mean by p/up? I am going to put in hooker headers.
