Currank5 submitted a new Build:

1980 K5

So it's been a while since I've had a K5. I decided it was time for another project and I purchased two trucks.

Last week I found an 84 GMC 3500 with a 454 and brought it home for $1600.

Last night I picked up a 1980 K5 with a 350 and an SM 465.

Plan this weekend is to remove the drive train from the GMC.

I plan on running the 454, sm465, np205 and the one ton axles in the K5.

The blazer is drivable as is and will run it around for a bit while I figure out what lift and tire combo I want and while I gather other parts.

Haven't really had time to work on the blazer but I've ordered and collected some parts.

Ran a compression test on the 454 and it had low compression in 3 cylinders. Pulled the heads and found a scratch in the #7 cylinder wall. Engine is at Wyoming Performance for a rebuild

I decided I wanted an overdrive with all the highway driving out here and picked up a nv4500. The guy I got that from had a ord crossmember for a BBC. Picked up a heavy plate 60 cover, spring plates and some hardware too.

Been looking at adapters for the nv4500 to attach is to the 205. The Advance adapters kit is 600 and requires cutting the tailshaft. Gonna solve the problem of the expensive adapter and shitty low range on the 205 with an ORD magnum box.

Plan is to get the drivetrain swap done first. Then do the axles, lift, steering, drive lines after. I'd like to get this thing on 37s with 4.88s in the one tons. I have been thinking about a 6" lift with ord custom springs. Gonna go crossover steering. Not 100% sure on what spring/lift combo to run so that's up in the air.

Interior is hideous so to get rid of the ugly red dash I have a Diy4x dash ordered. Feedback on lift and tire combo is welcome. Stay tuned for updates.
