If I recall correctly my friends 91 corvette ZR1 had the LT5 engine in it which was not a push rod engine. I thought that was one of the major differences between it and the LT1, but I could be mistaken. It had the “1st to 4th” servo in it. This servo was even on the late 90’s and 2000’s corvettes with the LS1. We should not be talking about 60’s technology here… We are talking about the same era in which they made lean burn so regulated it was no longer a viable option to be produced.

I would think this fact is highly skewed. Perhaps you are getting your pulse and gliding data from a vehicle that is horribly inefficient with a hideous drag coefficient… Most cars show much higher gains from this without doubling emissions... Not to mention, you can regain speed under low engine load thus further lowing emissions as well. I believe a stock Prius showed this best getting 117 mpg! Over 100%+ gain over EPA. I am not sure on the emissions on that test, but before you are going after people trying to conserve resources, I suggest you try to enlighten the masses who romp and stop to get from point A to point be… How many times to edomodders coast up to a stop light with the engine off while getting passed by and SUV accelerating to the light only to slam on their brakes. That is where the problem is… People in a hurry to get to a stop light and sit there…
We should probably get back to topic here. We have be sidetracking for a while now. Surely there are many other threads open on these topics.
