The reason I swapped:
1. 0 maintanence
2. Lighter than my iron head BB
3. Would need $3K in heads to equal what a ported 6.1 head is capable of, this $ covers my short block build by itself.
4. Shock and awe lol
5. Efficiency of the Gen III is unparalleled even by a SB
6. Its time to embrace the new stuff
7. To reliably equal the power my Gen III will make with a SB or BB I would need a solid roller valvetrain with lifters in the $800+ arena as well as rockers in the $700+ range. My 6.1 is going to use STOCK rockers AND lifters.
