Okay. Help a neophyte. The way I see it, whatever goes on in the combustion
chamber is completely ignorant of the length of the connecting rod, whether
the rod is 4" long or ten feet long (assuming the same crankshaft throw.)
The only difference I can see is that the longer the connecting rod the less
the angle of "push" it has in transferring the vertical thrust of the piston
to the rotational movement of the crankshaft. Where have I gone astray?

Subject: RE: 225hp
It is my understanding that going over 1.8 to 1 ratio would increase
the rpm that maximum torque comes in and going below that reduces the rpm
that torque comes in. This was from Hot Rod web site. Also look at April
2005 Circle Track, two 2.5L Ford engine builders Racer Walsh and Esslinger
both have articles discussing the increase in torque from the longer rod
theory. Racer Walsh claims to have increases of 9-13 hp and 18-21 lb-ft of
torque. I read all this after ordering my rods and pistons but it gave me
comfort knowing I wasn't wasting time and money, I hope. Barry
