"Home-Brewed" modified K Frame with B Body mounts

["Dart67"]

I think it might be, but it sure ain't by MUCH! I'm kinda likin the mods. That K member in the original post looks a little more lean than a factory piece and I really like moving the box over for header room. This is the kinda things Chrysler should have done.

That is because about 25 years ago, I did mods and fab work to move the k frame mount pads to use small block biscuit motor mounts. And also cut and boxed the k frame for a larger custom oil pan.

I never liked the small mount mounts and always had clearance issues everywhere with the 2 inch TTI headers.

That is what led me to fabbing the Engine Positioning/K Frame Cradle in this post: Added More Photos - "Home-Brewed" 67 Dart 440/512 B Body Engine Mounts


With that fixture, I was able to hold the engine/transmission in the proper positions and then fab the k frame pads to the engine mounts.

When finished with the fab work, I rolled the engine/transmission assembly under the car and bolted it in place.

Everything fit 99.9%.

The ONLY issue was the idler arm/drag link on the passenger side was still too close to the header tube and oil pan.

This was due to not getting the converted idler arm mounted at the correct angle. Somehow, I screwed up the angle on the fixture I made to hold the bracket in place using the information posted by @moparmat2000 here k frame dilemma.

I have a 340 Dart GTS convertible and I had to cut out part of the drivers side k-frame mount so the big block oil pump would fit on the k-frame, I still have that car with the cut...

that's what i did to put a 440 in a 65 dart.

I personally would have moved to a spool mount instead of using the biscuit style.
The spool mount small block to big block modifications has been done forever. As well the K frame was an offering from Mopar way back off the shelf, over the counter.
I did a small block K and put a big block in using biscuit mounts in 1990. I would however use spool mounts , mods were no biggie .. fit like a glove with factory BB manifolds, power steering and power brakes. I never moved the steering box or had to consider it. If I was to consider it geometry would have been a major consideration imo.

I have a spool mount k frame....

Personally, I do not like the spool mounts.

The steering box mod was done to accommodate using power steering with 2" TTI's. I am using a manual box now (my preferred choice) mounted in the factory position with the 2" TTI's.

Each to there own..

The spool design was great for retention in case the insulators broke. With the advancements in design, the "biscuit" design can stay together even if the insulator portion crumbles.
