One more thing I noticed, when I did my conversion, I was originally going to keep my T-10 transmission and re-build it. Because of the old style flywheel in the T-10, a 28.5oz harmonic balancer needed to be used. When I decided to go with the T-5, I had to use the 50oz harmonic balance. So from what I understand you have to match the harmonic balance to the flywheel, not the engine. If your using an old transmission with old flywheel, the engine probably needs to have the 28.5 oz harmonic balance. Maybe I was mis-informed but when I did my motor swap, this is what I was told. Good luck with it.
