Re: [Amc-list] v-8 intake manifold suggestions

[Matt Haas <mhaas@xxxxxxx>]

EGR is something you want on a street vehicle. You need a working 
temperature controlled vacuum switch (and a good valve) since it hurts 
performance and driveability on a cold engine. The EGR valve cools the 
combustion chamber slightly (exhaust gas doesn't burn much) which 
reduces pinging. On a performance engine, this lets you run more 
ignition advance or higher compression. On an emissions turd like the 
305 in my El Camino, it lets it accelerate up hills without sounding 
like a yard of gravel in a cement mixer. Another benefit of EGR is 
engine with it usually have an exhaust passage through the intake 
manifold which helps with cold driveability.
