[Land-speed] Compression Height, Ford Small Block, Of course...

[Rick Byrnes]

Hi Doc
Most of my motors have had piston down in the bore at least .010".
A lifetime ago I built a turbo motor with .160"piston to deck, to get 
compression lower, and it ran just fine and made more power than I expected. 
Speeds suggest around 400 HP from 2.5L.  While this is nothing by today's 
standards

My uneducated guess is that even with the smallish turbo I was using then, 
just created so much inlet turbulence that  the piston 
position/squish/quench became less important.

Now in later years the same engine with a properly designed piston with a 
large enough sump to get compression down to where I wanted, made lots more 
power, but many other parts had been changed as well.  Wayyyy more power.

So, I'm gonna say for a street engine of some unknown HP. down in the bore a 
little (like .060") probably would be just fine........
go for it..........and have some fun
