I know it was never done factory. There were th350's behind the bastardized olds 5.7L diesel. Besides the governor, torque converter, and making a kickdown cable bracket, does anyone see a problem with this? I understand longevity won't be the greatest, but I have a 350/203 and a 6.2, and I have a very very tired 350 gasser and a broken case th400/np208. This sure makes a good 6.2 + good th350 seem like a bright idea to me.
