Wow, I have seen on TV a dyo test on doing that to headers and they smashed one tube on number seven a bit, looked like more then a bit to me watching on TV, but, there was zero power difference, then they did two, 7 and 5 , nothing changed.. yes, that small starter will make you much more happy, spins the engine much faster and I bet at a lower amp draw then the older bigger ones. Yes is my vote
