That is what GM built them for....GETTING THE CAFE NUMBERS UP

As far as power goes....they were a real turd....

About 130 hp IIRC in the 1/2 ton.

Dual exhaust and fun to drive...

A banks turbo kit would wake them up a bunch.....but still.....by today's standards.....A real slug......

You can do a rebuild on one of these and add a Banks turbo (Seen on ebay off and on) and make 160-180 HP and get a decent little runner.

A K5 Blazer with one is a good little hunting/camping rig and can easily pull a modest size camp trailer....(READ THIS AS NOT A BIG ONE) 16' OR SO.....

Have fun

Here’s my red block formula I would use if the nickel theory is true… tell me what you think…

1. Crack free rebuilt 6.2 redblock.
2. 18:1 coated pistons.
3. Taper Main Bolt holes.
4. Twisted Steel Girdle.
5. Improved Heads.
6. Brass tube between valves. (Lock n Stitch)
7. 33 plunger Injection pump.
8. Compounds
9. Downpipe straight out of hood
10. Ho 130gpm water pump
11. 9 blade dmax fan
12. Paradox by design
13. Quadstar upper plenum
14. Quadstar oil drain
15. Quadstar Valve cover braces
16. Light porting of the exhaust ports
17. Port all burs
18. Dual thermostat cross over
19. Innercooler
20. Fass lift pump

Anything else yal think should be thrown in?
