I have a 2001 f350 6 speed and want to make Around 450rwhp. Is that to much for the stock bottom end? What would bring me up to this hp, right now the motor is all stock.

 

depends on what rods you have, need to find that out first. i have seen both PMR and forged rods in an 01

 

What is the easiest way to tell If I have forged or pmr rods. Isn't there a plug by the oil cooler I can pull and look?

It has pmr's

 

Personally I wouldn't shoot for 450. I know a lot of people have but thats just me. For 450 you will need at least some 160/100s or 238/100s. You will also need a turbo, along with the basic gauges, intake, exhaust and chip
