Rod ratio? SBM is so well endowed
I've rune a "327" SBC block with 4.250 stroke and a 6" rod
4" stroke with a 6 and an eighth would be heaven for the SBC guys
If you want to better your rod ratio (and I became a long rod guy)
just use a longer rod and a smaller pin and a shorter compression height piston
there is lots of room to do this with the SBM
cam timing changes do plan on some testing
