Today, dollar for dollar, is the 318 faster than the 340 ???

It's funny, I never see any machine work being done in the pits when they run those 12,000 plus HP top fuel engines. I'm sure they may do a little.....mostly all I see are bearing and ring changes and the like. I guess they must not know the speed secrets of doing machine work on builds. You'd figure with the pounding those engines take, they'd want everything perfect, yet they run a lot of the same hard parts over and over. And win.


Have you never heard the motto in the fuel pits??? I may not get it exactly as they say it, but this is close. Measure it with a yard stick, cut it with an axe. There isn’t much precision in a fuel engine. Clearances are humongous. Pro Stock is a different horse altogether. You don’t see them slapping new bearings or pistons in at the track. They have much closer clearances and tolerances than a fuel engine does. They run water thin oil where a fuel burner uses a 70 grade oil that when up to temperature is more like fudge than oil. Two different beasts for sure.
