87 k5 blazer and 84 m1008 cucv

[ArchonBrutal]

I intended to feed the 1008 running gear to the blazer and swap motor and Transmission for a ls3 and 4l80e. Now that both are in my driveway I'm having mixed feelings. I can fix the fuel issue in the 1008 and have an awesome work truck. And motor/Transmission swap the blazer on stock axles frame and make it more comfortable as a daily, that goes fast when I want it to.

With that idea in mind, am I setting myself up for breaking something on the blazer if I don't do anything with the axles and frame? Do you have a better recommendation on motor or transmission? I'm looking for power but still keeping "daily driver" in mind.

I'm looking for pointers on where to start with the fuel issue in the 1008. It starts fine but will die without throttling it a bit. It is a 6.2l diesel.

I cannot afford to shelf quality but I do have time, for now.

I can add info/pictures as needed when I figure out how to navigate this site better. Also, sorry if this is in the wrong place forums are not my strong suit.

Lots of us have driven stock blazers without issues. They are fine rigs in stock form (though I'd avoid the 8.5" G80 Gov-Lok carrier that some rear axles have). Parts start breaking when the truck is abused or it gets large tires. If you treat it well, it will treat you well. If you intend to beat on it, I'd swap in a heavier rear axle.

Your drivetrain choice is fine. The 4L80 wastes more power than a 4L60, but it is stouter. Again, your driving style makes a difference.

Elaborate on this. Does it just need the idle turned up?

That engine has two idle adjustments, and the cold idle is set with a solenoid. Given the age of these trucks, it's common for the cold idle solenoid or its temperature switch to have failed. If so, you can repair the circuit or simply raise the speed of the main idle.

Does it run perfectly aside from stalling? Or does it have other issues?

As far as the axles go, thats a very subjective question. It really depends on what your final goal is for the Blazer. As @campfire said, if your just gonna cruise the blazer with occasional light offroading like dirt roads, or the beach, then the stock axles will serve you fine with regular maintenance.

But if your are going to go larger than 33's and beat the rig in the mud or rocks (or tow heavy loads), with off camber scenarios, then you would benefit from the 1 ton axles. But much more will be needed to get good wheel travel and manageable steering geometry.

the one ton axle swap has been covered by many build thread in this forum. As well as mine. if you plan to move forward with the swap, then read a ton here, and plan it all out. Buy all the parts you need for a smooth swap. think about springs, lift, shocks, brakes, e-brake, drivelines etc... All that needs to be considered before you start ripping stuff apart. Depending on the mileage on the axles, this would be a good opportunity to freshen that up or rebuild it. Bearings, seals, u-joints, spindles, brake shoes/drums/disks...
