If you already have the stuff, just send it! That kind of power overcomes a lot of things that aren't perfect. It will be ultra fun to drive. It will use a truckload of gas.
If that converter wasn't built for the level of torque his motor is putting out won't it cause the TC to stall way too high? Sounds like the issue I was having towards the end of last season. I have a 10" converter that was built for use behind a small block and I when built the 512 I reused it. Chassis dyno results were lackluster as the torque curve wasn't flat at all behind the peak number. Still hashing it out...
