i heard that using longer rods will help top end, but how do you know what size to use without running into problems? looking for new rod for a built h22 turbo

 

Eagle offers some longer rods for the B series but I don't know about the H series. The only way to know how long you can use is math my friend. Use the deck height and get your stroke/rod length/compression height to figure it out. If you can get some longer rods, I'd imagine that you would have to order custom units (big $). Then you would have to order custom pistons with a different compression height (again, big $). Unless you deckplated your block (once again, even bigger $). HTH
