my cousin has an 00 chevy single cab laying around. he wants to do a duramax diesel swap but doesnt know if it would fit. other then maybe reinforcing the frame what else might need to be done?
any help or links would really be appreciated.

 

first second is that thang a 1/2 ton needing to reinforce the frame?

 

not a 1/2. plans to reinforce are acknowledged.
