Emissions question (and oh gawd, tires again!)
Hey guys. I've searched through my shop manual and this isn't covered, so... 1980 Bronco with 351.
That thinge that runs from the exhaust header to the air intake tube... what the hell is that? Well, mine busted. And I figure since it's emissions crap(?) to pump exhaust back into the air intake, if I just cap it off, so be it and I'm done. Is there any reason not to do this? Power, mileage? Emission are not tested where I live.
Also, ANOTHER 35" tire question. My 1980 Bronco is stock and sits on 30 by 9.5 by 15" tires. However, the tire is actually only about 28.5" tall, maybe 29" when spanking new. Okay fine.
The top of the wheel well from the ground is 33" tall and the wheel well is 33" across.
Okay, so, assuming a 35" tire is really about 34", if I divide that by two (for the tire above and below the centre of the hub), I get 17". Well, from the centre of the hub to the wheel well in all directions, is about
18.5" (sitting on my 30"s) . Thus, 35" tires would clear with about 1.5" in all directions. Is this right, or crazy? And if right, would it be bottoming out a ton? I don't use this truck to 4WD off road per se, but I do haul a lot and two a lot.
Thanks everyone for any advice!
