318 compression test results

What you need is;
a TC balanced for a 360, or
a flexplate for a 360 and a zero balanced TC.
Pre 1967 TCs have a different spline count inside, and a different diameter crank pilot.
This means you can use any NON loc-up, post 1967, 318 convertor which I think are all zero-balanced, , on any other post 1967 engine, with the correct flexplate.
You can knock the balance weights off any TC to make it a zero-balance TC.
