Coan low volume I had was stock 350TH pump gears and housing milled down.Coan told me worth 6HP
@ wheels. I didn't gain 1/8 mile was told would be more of 1/4 mile improvment.I put low gear set in
at same time I think it made my converter that was already on the tight side tighter{lower gear set makes
converter tighter because multiplies torque more} and cost me any gain I should've seen,only difference
I could tell was normally running 45-50psi in front tires had to drop air to 30-35 to slow
reactions times back to same spot on tree.BTW if you want low gear set for 350TH they are made
from 700R4 planertary modified to fit 350TH If you have the skills you can make your own.
