I am curious if any one has experimented with connecting rod ratio's in the Y block to gain optimum Piston Dwell.

Having fitted a Cam which is encouraging the engine to operate much different to original, I would think a longer rod would increase dwell to ensure complete combustion at higher engine speeds. More torque! Though piston speeds also becomes altered which works well for compression yet can create problems of detonation post ignition.  
I believe old smokey can be quoted saying "stuff a rod as long as you can get into it".
 For example my 292 has a ratio of about 1.9:1 and a windsor  302 has a ratio of 2;1 .
However the windsor has a larger bore stroke ratio as well. 

So with all the options of rods and pistons available I found a set of Flat head rod at 7" with a 2" rod journal, H-beam type.
I could then stroke the 292 crank to 3.4" or 3.5" at 2:1 or more.
Does anyone know of sets which would fit without grinding the journal down as far?
