I am going to be doing an engine swap for a buddy. We are pulling the 350 from his 3/4 ton chev and putting a 12 valve cummins in its place. Just wondering what advice you guys may have to aid in a job like this ? Should I box the frame ? If so all the way or just partial ? Im sure there are alot of variables and I just want to make sure that i dont miss anything. I know the cummins is going to put out a hell of alot more torque than the 350 so there is going to need to be beefed up a little more in the frame to stop excess twisting right ?


Thanks for your help.

The cummins is around 1100lbs to, so suspension mods will be needed.

You will need 1-ton axles. This is probably not optional.

Diesel Frames need to twist. This is to handle the torque. Boxing the frame makes it rigid, which will probably lead to cracks if not done right.

I dont want to get someone else to do it. I am asking for ideas so i can learn myself how to do it. Its not rocket science , i just thought there may be someone who has done it before. Anyways , i aquired a 3/4 ton dodge diesel frame and running gear for cheap so i might just mount the body on the dodge frame. Thanks for the suggestions though.

I know , have to use a chain block and large wood beam. Pretty redneck style engine hoist. It was bowing pretty good though.[cheers]
