I got a 4bbl M1 on the way for my 408 and I'd hate to choke it with a 2bbl adapter so I'm thinking about a 4bbl throttle body. Any tips, suggestions or advice? What good throttle bodies are available? The Mopar and Accel 3bbl are discontinued.
I'd like to retain factory cruise control so i know a bit of linkage and bracket fabrication will be needed, spacers to clear fuel rails, rewire senors, IAC solenoid...... Am I missing anything?
