1405 carburetor

Unkle Krusty · Mar 22, 2025

Mostly carb questions. I am reading the instructions so have some things figured out.
Which way around does it go? Does the Edelbrock badge go to the front. If so part of the controls hit the inlet manifold, and I would need a spacer about 5/16. I will study the setup a bit more tomorrow. I will use a push / pull cable for the choke. I need to study the 1481 adaptor, once I get the orientation correct. Any tips will help.
And lastly, I finally found tne torque for the head bolts. Haynes manual says 105 thru 77, and 95 for 78 on.
Mine is a 77. I think I read here somewhere that 95 was correct.
Some pics so far.

Badge goes on front.

Myself, I only torque to 95 lbs.
particularly with production used bolts
and still watch for stretching while torquing.
particularly with stock used bolts.

I also use only composition gaskets on used engines that
are not freshly machined.

Yes, spacer so the fast idle cam link clears.. Looks like a big vacuum leak if you don't plug the hole in the back of the carb...

A friend just bought a 'Chinese' #1405, $AU270. I removed the top to have a look & check the f/level. Looks very well made, polished, comes with some extra jets, hose clamps, mounting studs with nyloc nuts, two base gaskets & rubber covers for the ports.

Thank you men. I will study it some more today. With the instructions I should get most things figured. Will know more when it is back in the van. Doig a test fit now, and will probably remove the intake manifold to obtain a bit more clearance when installing the 318 and 727 back in the van.
95 on the head bolts sounds reasonable to me.
I have both metal and composite inlet gaskets. The composite cover the half moon shaped holes a bit better.

They make an electric choke kit for the #1405. Basically makes it a #1406.

Doesn't matter how well they're covered. It's a casting relief for the heat crossover, and goes nowhere. The center holes that are the heat crossover must be sealed of course.
