/6 in V8 K-frame

So you have a /6 car and a V8 K frame and want to put the V8 frame in the car while keeping the slant six until you do a V8 swap?

That is exactly the situation. I was hoping it was just a matter of different engine mounts. The /6 car is a 69 barracuda, donor is a 73 Swinger. I already swapped the brakes, upper and lower arms, booster and master... Swinger has power steering also. Wanted to redo it a piece at a time with the V8 being kinda the 'last step'..
