I've ran tunnel rams on the streets for years and years and years, I had a 2x4bbl tunnel ram on my daily driven work truck for a couple of years. Stock converter with an automatic to boot.
Never had any troubles, cold weather drivability was BETTER with the tunnel ram which flies against the face of wisdom I suppose. I had power brakes in almost every vehicle as well.
Daily driven 3/4 ton clubcab with 1 ton suspension....
My Demon had to pass AirCare emissions tests every year, it passed with flying colors year after year, no detuning whatsoever, I just drove it on the rollers....
My Coupe was driven tunnel rammed for 10 years before the switch to EFI....
Even had a daily driver for my wife that was a 2x4bbl tunnel ram car.... she drove it to work for years trouble free...
