Mike, for detailed info on your 8-stack EFI, the setup used 4 TWM throttle bodies and a brainbox all sold by Dennis Quella's 'Pantera Performance' in Colorado. I'd go to him via telephone rather than the internet. The system is popular and arguably the best on the market even today, but Dennis is old-school and works better on the phone than at a keyboard.
