Why??? ...MORE POWER
If I got a challenger R/T with the 5.7 Hemi Could I later bolt on the better flowing 6.1 parts? When rebuild time comes can the block be bored/sleeved to match displacment? What is the difference with the bottom ends besides displacement?
Is it like the GM LS engines where you can make a ls1 an ls6 or an ls2 or is the 6.1 a whole different animal?
