I think Carroll Smith said "Horsepower sells cars, torque wins races."  I think 
it's fun to look at the HP figures, but the bottom line is the torque reading.

This is interesting, to say the least!  I've learned that dyno operators 
can - like great accountants - make figures lie and liars figure!  This 
comes from a VP I spoke to at Superflow, where he said that by changing a 
few programming parameters and doing a few different tests you can have a 
15% swing of HP produced - without breaking the "rules" of dyno operation.

I use John Dodd's dyno - he tests using perhaps the most conservative 
methods and probably gets the lowest HP readings - but he is notoriously 
closemouthed about what engines he tests produce.  I think that if he 
didn't have to let me know what MY motor did he wouldn't!  But his 
customers sometimes let a few things slip...

 From conversations I believe that  great Twin-Cam will produce up to 180 
HP.  Perhaps a Hart will get a bit more  but not much.

I believe that fully legal FFord motors that win major championships - 
Monoposto and modern racing - make no more than 112 - 115 HP.

I think that Junior engines - and many other Ford based motors - can get up 
to 100 HP per Litre.  This gives a great Junior engine about 110 Hp.  I 
think that pre-cross flow 1500's can get about 135 HP.  A really good 1600 
cross-flow can get 160 HP.

Keep in mind that by changing the way that the test is run, that FFord at 
112 HP could easily be given a printout showing 129 HP.

The best dyno continues to be a really long backstraight...
