So first thing, I have researched a bit but didn't find much in the way to answer my question. When replacing rods in the engine, whats the difference between I and H beam rods? Yes obviously one looks like an I and one like an H. Any main reason to choose one over the other?

it's a Corvette forum but it's the same concept

 

fantastic. that's what i was looking for. thank you. and yes i know wrong forum

 

h are normally stronger and require notching of the block but most i beam rods you do not need to notch the block or girddle

 

hmmm. why do you need to notch the block? (stupid question i know but humor me, i'd rather do my research before buying random parts)

 

This is not research. This is spoon-feeding. If you search you will find that some rods need the blocks notched for clearance issues.
