225 long rod stroker, HELP

JoesEdge said
Wow...I think I need to do some reading, because all this time I've read that longer rods are better, but maybe that's for V8 engines? I even read about the 198 rod in a 225 trick too.

In the past I've read that longer rods flattens out the torque curve. Back in my Ford days (in the early 90's), the theory was proven with long rods in 302's. If cost wasn't an issue, it was the the way to go. The goal was to improve the rod ratio.

I did a preliminary search on the topic and found the following article, but I know I should keep reading.

Maybe the whole rod ratio debate is almost asking like which oil is better. LOL

By the way, a fuel injected Slant 6 would be cool!! Sure, not cost effective but cool!

Maybe give these guys a call and see what they say:

These guys may have some input too:

At the risk of oversimplifying things...some engines are born with shorter rods than others, and can benefit from a longer one.
THE 225 IS NOT ONE OF THEM...period, end of debate.
The engine is insanely oversquare with not nearly enough piston surface area to adequately work the crank without massive amounts of leverage. The longer rod decreases this leverage, reducing angularity in the early stages of the power stroke...exactly where it needs it the most.
When someone finally offers a cross flow, overhead cam cylinder head for a the Slant that is capable of supporting 10,000 RPM, there will be some merit to a longer than stock rod in the 225. Until then, it is pure idiocy perpetuated by people who have too many fingers on their hands
