Longer than stock.

Someone will correct me but I think stock is 4.8". I'm using 5.0" rods on my 2017...something like that anyway. The point is if you increase the stroke of the crank the rod angle changes. Picture a cutaway view of an engine with the rod on a stock crank with the crank at it's highest in it's revolution. The rod will be pointing down toward the cylinder at an angle. Now picture it with a stroker crank, the angle increases because the connecting point on the crank just got higher but the connecting point on the piston stayed the same. By using longer rods the connecting point on the piston moves out reducing the rod angle.

Longer stock rods?

 2017cc if 78.4 crank and 2007cc with 78.0 crank.  Lots more torque =
than what you had before.  Because of the rod angle you should consider =
using longer than stock rods.

 -Dan =20
 (...who is also building a 2017cc)

   That is a good idea, Shirley, about the engine in Ruby, the Ghia. It =
is almost brand new. And if you will send me the Porsche engine, Dunc, =
I'll pop that booger in as soon as I get it.

   I do think that it will go this way: Tomorrow, probably, I will pull =
the engine and take it up to Wayout where he says that he has all the =
tools to do machining and build. We will, at least, tear it down and as =
Will suggested, see what we have.

   Then I will either build the new engine there, probably using the =
90.5 pistons and cylinders, or take the parts and bus down to Chuck's =
and build it there the week before T@P.

   I have to tell you guys that it fees really cool to have four =
engines offerred as loaners, not even counting the Ghia. Thanks y'all.

   So, if I use the 90.5s and I have a 78.4 stroke, what will the new =
engine size be, and what is the formula, anyway? Multiply, add? I have a =
1914, how do you get that number
