Oh wait! How will I ever make it? That 406 SBC will surely overheat! LOL!

That’s crazy, mine weighs in at 7400 loaded for a trip. You have a lot more room for sure. Great looking setup.
Once I figured out a lot of my issues, I’m pretty happy with my 400sbc. Ran super good to and from Texas in the heat for 8hrs straight one way and with the AC on the entire time. Not a single overheating issue.
Yep. It's heavy. Empty with driver: Front 3100 Rear 2260 Total 5360 Ready for camping with driver: Front 3310 Rear 5490 Total 8800 Scary that it only put 210 lbs on the front axle. When I pull my atv/ sXs trailer I'm in the 12,500 lb range
Only if the plastic fuel filter doesn't burn it to the ground first!
Nice, but lose that plastic p.o.s. fuel filter.
Is that fuel filter really that big of a deal? I’ve ran hundreds of those and never had a single problem. Hell, even Derek from VGG uses those on every car.
They are only an issue if you leave them on too long, and they get brittle. Or you already have an engine fire, and the filter melts, causing a bigger fire.
Saw this walking the junkyard today, the engine looked big? Maybe I was ahead of myself and thought it was a 400 
Big block that has the A/C compressor brackets still on. But the truck doesn't have A/C. So the fat block was swapped in.
Chances are that this motor already has at least 400 cubic inches within it ; does that count ?
All the extra metal on the engine is just there for ballast to help keep some weight on the front end when heavily loaded…
If I would have seen that, I would have pulled all of the brackets.
I didn’t spent much time and only brought the tools needed to remove what I was after. This was one of two trucks in the yard.
Would you go get that 400 emblem for me? My grille is missing the emblem
Sure, I’ll see what I can do!
I run headers on my 1978 small block 400 K5 Blazer, not because I am a big header fan or trying to make it a racing engine, but rather to help offset the poor cylinder head design. The last thing it needs with those poor cylinder heads is the stock log jammer exhaust manifolds. I am not really qualified to say if or by how much it helps, but it just seems like a good idea given those cylinder heads.
Just read this thread from start to here; whew, my brain hurts. I too have been "blessed" w/a sbc 400. It was not by choice, just came already installed in this "oxidation special" I bought....I have an average 350 (prolly 300hp) ready to go, but I'm just too lazy to transplant if the 400 is gonna be a runner... time will tell, and I've got a long way to go (new inner and lower inner cowls to install, plus re-wire before I try to fire it up..... it does turn over, so I've got THAT going for me! Guess I better get a heavy duty temp gauge installed first! Here's MY train wreck:
Oh wow! My pos 400sbc pulled my 8800 lb. butt to 10,300 ft without overheating! (like it always does, nothing different to see here!) Lol
