You seem to know a lot about these trucks, I was wondering if i would have a
power problem I wonder if some of these places you can buy m35,s would do a
swap. also would the 6.72 gears be to low for those 6bta engines ? I dont think
they rev much past 2000 rpm . Maybe the overdrive might be enough an a
standard or auto trans to make a differance.l
