wristpin holes the same size i want to use my 5.9 vp rods and 6.7 pistons on my ppump 24v thanks
 
do you know how much weaker they would be and also what is the standard bore size on the 6.7?
 
Don't forget that the wrist pin to crown diminsions are different. The hole in the 6.7 piston is about .1 closer to the crown.
