How much power are you looking to make. All rods will be weak at a certain power level. The increase in wrist pin size I believe is very minor (I also had an additional oiling hole drilled into the wrist pin side of the rod for additional oiling per the mopar performance manual). I'm not sure what the stock forged dodge rods are rated to but there's plenty of people making 300+ hp on them. If you're looking to run crazy power like 400+ hp you may want to consider a different rod. As for bore size you will need to check with your machine shop for bore measurements compared to the size of the venolia pistons. I believe forged pistons will require more slack (clearance) than stock pistons as they tend to expand more (and will be noisy when cold due to piston slap). So your cylinder may need to be bored a very small amount depending on their trueness and the clearance between the forged pistons. Good luck.
