Howdy y'all I just bought my first dodge d250 it's a 91 gas model that I plan on converting to a cummins Diesel engine and swapping out the rear axle for a dually axle. I'm hoping that a 5.9L or 6.7L will fit in it.

 

Welcome to the forums! You can find a ton of helpful info here. I'm a 5.9 fan myself but either or would be a sweet swap

 

Welcome to the forum. Check out the 1st gen Ram section.

 

Thanks y'all. Car ram rod what's the biggest difference between the 5.9 and 6.7 besides the size?

 

We'll my biggest reason for the 5.9 is the fact that it's a tried and true engine. I'm not putting down the 6.7 I just dot know much about it. I do however know that it didn't come out till... I want to say 07 and the 5.9 has been around way longer. Making the availability for parts pretty easy. From what I've heard the 6.7 is great but I can't give first hand experience
