That is an EXCELLENT point about "pure stock" in a racing environment. The same basic rule applies in road racing also. So WHAT is a "pure stock" engine in that world??

Not allowed any machine work, PURE specs. So you find out where a HUGE supply of intake valves are, pull up a chair and start measuring!!! Your looking through the boxes of valves for the few that are "perfect". Same for all the internal engine parts. Not all pistons are "created equal". Each piece of wieghed, can you say "engine balanced"? Make no mistake, in the "big leagues" "pure stock" takes on a whole new meaning.

The "big dogs" have the "connections" that get them access to the "box's" of engine parts to search through. Without the connections, you haven't got a chance!

As Hal states, Speed is a relative term. Even by todays standards a "really" pure stock car off the showroom floor and hit the track with it, that can run 14's in the 1/4 is a FAST car!

I think it was Car and Driver in 65 that clocked a "stock" GTO to 100 mph in 11 seconds. Right,,,,,,and I got a bridge I'd like to sell you! LOL
