The wrong question. Several differences that make each unique. both have their pros and cons but they both, if treated right can be 1,000,000 mile trucks

the reason I ask is i have a chance to inherit either my dads 93 12v or his 93 that he droped a 24v in......i really like the sound of the 12 along with the way it drives....Im new to the diesel world of cummins. My first diesel was a 7.3l powerstroke.......which i hated just for that fact it was a Ford.....and it gave me many problems.....i just want to make the right decision because dad passed and what ever i dont take is being sold unfortunatly.....

well i have had both and personally i like the 12. it honestly is going to be up to you. a matter like this goes beyond performance, reliability, and mechanics. this seems like a sentimental kind of thing. drive both and whichever one you think is right for you then claim it.

You mentioned a '93 with a 24v under the hood? That'd be prety cool. If it still has all 24valve parts it can be chipped for more power. However the 12v can be modded (to a point) for free. The 12v of course is a little more simple for tinkering on but I'd say either way you'll like what you end up with. I'd say another factor to look at would be overall cosmetic condition. Take both for a drive and take the one that suits you. Good luck on your choice.

I'd go 12v for the fact if you need a part you will have an easier time getting the right one but a 24v would be sweet. My truck has a crack in the block n I wanna get a 24v n p-pump it for my truck one day. But it's your choice I agree with crazytexas I think it goes past the truck itself but either way you will have a part of your dad in either one.

12v got my vote. due to simplicity and best netted fuel mileage among the cummins series "normally". good luck, im sorry to hear about your dads passing. may he RIP.

My cousin had an 01 with stuff done to it n what a ride. We turned onto the highway, Punched it on max tune n she smoked both tires through 3 gears with no help from the brakes down the highway doing about 65mp/h.

I bet that 24 valve nets better fuel economy in a truck that weighs 2,000 pounds less than what they came in.

Allot of 24 valves can net 20 if a manual and usually horrible in an auto.

But you put that in a first gen and they should get better fuel economy. They breathe better, have allot higher injection pressures, and are computer controlled.

I love 12 valves because it is more of a challenge to get it in the higher horsepower and still burn clean category. But a 24 valve is a quicker motor with less fuel or mods because they have the ability to breathe better.
