things not to forget when putting a engine from a 2wd in a 4wd

Be sure to use the correct block mounted engine mount it will save you time and frustration. Next I will have to figure out the downshift linkage since the motor is out of a manual rig.

Swap the carb if you have the other. Just my to cents.

I thought about swapping carbs but my other one is a 600 cfm edelbrock with manual choke and I prefer rochester q-jets I figure I'll just go to pull and save and get the linkage or another q-jet

I like both of them. But thats cool i guess i never thought bout the motor mounts.

I wonder why the motor mounts would be different?

What year of rig are you working on? What is the difference that you found in the block bracket between the 2wd and 4wd?

I'm working on a 75 jimmy the engine was out of a 79 or older truck nut sure though it did have a electric oil sensor and electric water temp sensor but climatic (hot air) choke. the mount seemed to be about 3/4 inch wider than mine, if I got one whole lined up the other was like 3/4 inch too far over and when I did look at both mounts off the engine they didn't match.

sure your motor mounts arnt shot and dropped in the shells. ?

 

[duanel]

no the bracket that bolt to the block were obviously different (when sat down side by side on a flat surface) and once I changed them they lined up with no problem

 

[sweetk30]

i have heard there is a diffrence from non brace rod in the middle of the bracket to block to with brace rod in the middle.

someone could of removed the brace rods or swaped mounts and had slopy mounts . who knows.

Here is a picture of what I am working on, I am getting close to test driving it.

Yup---certain years & models had different engine mount bracketry--passenger car ,2wd ones sometimes were 1" "shorter",the distance from the block to the through bolt hole was an inch closer to the block,than some 4wd truck ones were --some were offset to one side more also as you ran into..the ones that had the "truss rods" bolted to them were "special" too..
