Hi guys I dont know if this is the right post for this post but heres what I got

I was wondering If i could take a 87 chevy 1500 and put a 1st gen cummins in it some what easy or is it just going to a pain. I will gladly take any info you guys have to offer

Thank you

 

They're all a pain bud! No, If you like to tinker on cars you should't nave a problem, just time and a few $$$. Check out the "diesel conversions" section farther up on the home page, great info on there

 

Ya look at my post in diesel conversions I'm putting a 93 12v in a 89blazer same body and frame u have 87

 

installing the motor isn't the problem. it would be the front end holding the weight (it is 1100 lbs) that truck either had a 10 bolt or a 44 the cummins has a gear driven steering pump, so there is no forgivness in the components. you should also beef up the frame around the box. let me tell ya it's a hell of alot better to drive. I would look around for a dana 60 for up front,mine has worked flawless. good luck on your swap

 

I have a cummins in my 79 chevy U better reinforce the frame mine is twisted pretty good in the rear one side sits a little over 2 inches higher than the other side. I just have a stock 10 bolt front axle no problems in 2 years in the rear I have a disc brake dana 70

 

Ha ha that's funny my 10 bolt front lasted 10 min in the sand I'm going to a dana 60 now

I put mine in an 89 2500 and still had some adding to do to make it stronger if you could find a 3/4 ton alot of the beef is already there

 

Here's a picture of how the Cummins fits in my 1990 square body Suburban. It's backed by a NV5600 6 speed manual and gear vendors overdrive.
