A couple weeks ago I put together my 8 3/4 and put it into the dart.
This weekend I started on my 4 speed swap, I put in my clutch and brake assembly, pilot bushing, was about to put on my flywheel and I just went to double check to make sure I didn't need a weight on it. I saw on the Mopar forum that some 318 cast cranks we're so out of balance that they needed a weight on the torque converter. I had remembered seeing a weight on my converter when i took it out so I went and checked and sure enough there was one on there.
So I went under the car and scraped some caked on oil and dirt off the casting numbers and this is what I found.
So my boring 318 car is now a 360 car! I assume this was a swap from back in the late 70's or 80's. I mocked up the trans and cut the hole for the shifter and linkage. My driveshaft is getting shortened and Now i just need to wait for the 360 weight from Brewers to come and then I can start bangin gears!
