Frenchie:
Apart from the illegality of removing emissions equipment even
if your car is not emissions tested, there are the following downsides:
1. Reduced fuel economy. The EGR valve reduces pumping losses at
cruise, so expect a slight reduction in your highway fuel economy.
2. Your oxides of nitrogen (NOx) will increase. Many states
exempt older cars from emissions testing, so you may not care about this
point. If your car is subject to emissions testing where you live, you
will not be able to register it.
3. Reduced resale value. An original car is worth more than a
modified car, all other things being equal. Removing the emissions
equipment will have a negative impact on the value of the car if/when
you sell it.
Upsides:
None. The EGR disconnects itself from the engine at idle and
under full throttle, so power stays the same with it on or off the
engine. You may need to adjust your mixture slightly.
Removing it is trivial. Plug the various vacuum orifices on the
carbs, remove the EGR and plug the hole in the manifold (3/8" NPT ?) and
plug the hole in the head (uses a metric oil pan drain plug as I recall,
don't remember the thread size)
Cheers,
Vance

Is there any problem with removing the EGR valve and plugging the hole?
