84 Blazer 12v build

Thought I'd share my Cummins 12v build with you fellow Chevy members. The 4th of July I picked up a fairly clean 84 Blazer without a engine. Brought it home, took the 35" tires off and sold them. Stripped out all the wiring that wasn't needed for my Conversion. Since I can't post pictures yet i'll have to do that when I'm allowed.


I then thought since it was going to have a few lb's extra on the front and a lot more torque I better beef up the frame. Picked up the kit for the frame and engine crossmember from Robbonneyfabrication.

The transmission I'm using is the 47re from the Dodge and since it's a electronic controlled one I found a Standalone Controller from E Transcontrol that is real user friendly. It doesn't need a separate VB or Laptop to use it, the unit has buttons on it that you program the Gov. pressure, TVA Pressure, OD, and Torque Converter lockup.

The Dodge has Hydroboost brake and I decide that I would also install it on the Blazer, then there would be no need for the vacuum pump that's on the Cummins. I found a vacuum pump delete that someone was making along with a new Power Steering pump.

Put a 12v/NV4500/205 in a 86 K5 blazer a few years ago.

Boxed the frame, made mounts using Gen 2 motor mounts & engine/trans crossmembers

It would have saved a ton of time to order Rob Bonney's kit for the conversion.

A fully dress 12v weighs ~1100 pounds so upgrading to 1 tons is a must. Gary made the comment a cummins like to break everything south of the bell housing for fun. So upgrade accordingly.

I've owned the truck that the engine came out of for 11 years so I know a lot about them. What I always say they make Dodges for conversions.

There was a B&M Mega shifter that came with the Blazer so I wanted to use it. Decided to make a custom Console to mount the shifter and lay arm.





Cleaned up the engine, replaced gaskets and seals, installed the vacuum pump delete and power steering pump. Also adjusted the valves since it had about 40,000 miles since last adjustment.

Update

I got the shifter that was made for a Th350 connected to the Dodge's 47re trans. Ran all the wiring for the transmission controller.

Took the driveshaft to the shop to have it shortened since the trans is where it needs to be. Installed the Dodges intercooler and radiator in the Blazer radiator support along with the trans cooler. Filled the trans with fluid and the radiator with coolant.





Put the Dodges hydroboost on the Blazer and bled the brakes.
