I don't mean to hijack the thread. I am installing the motor, transmission and TTi headers all at the same time. I was thinking of laying the headers in the engine bay and sliding the motor in and working the headers in at the same time. I am doing this all on a hoist, so it probably won't be an issue installing them from underneath. What do you think? 73 Dart Sport, 408 stroker, GM 200R4 tranny, TTi 1 7/8 headers.
