I know this gonna cause more chaos but here it go's....
A longer con rod makes the piston dwell at TDC and BDC longer, more cylinder pressure is generated before the piston starts to move away from TDC. Thus your motor will make more power.

In theory this is correct, in actuality its not always true. its kind of like compression ratio. The more compression is better.. Well not always, it is to a point. 9:1 to 10:1 creates more of a difference in HP then 13:1 to 14:1. This also applies to rod ratio and rod angle. Saying cramming a longer rod is always going to have more HP is not true. If this was true then new motor designs would have rod ratio's of 2.0+ . but they dont, why? Because for one, there are many things at play, weight of rods, piston weight, ring lands LOCATIONS, distance of the top ring to the combustion chamber, distance between 1st and 2nd ring.. All of this has a play in HP, it doesnt make sence to gain 3hp with a rod ratio then lose 5hp because all your rings are crammed up at the top of your piston with heat stress. Its not that people are trying to build with all the rod angularity they possibly can, its they are trying keep it with in reason or within spec. The normal standard is considered around 1.54 or more. This is seen in the 351w stroked to 4.17" off the top of my head I believe the ratio drops to 1.4's, here we have a serious need for a longer rod at the sacrified of moving the piston up, a shorter piston, less skirt area, ect ,ect.. In a stock 351 it is pointless, if anything its going to hurt you. It also gets back to the how much money per hp does it cost. 300$ rods custom pistons 400$, now you have spend 700$ for probably 3hp? Although my figuers may be a little extrem you can get the point. It just seems pointless from all aspects.
just my two cents, ok you guys are free to attack my opinion now
