metal, I'm swapping out my 4" final drive pulley for a 7" final drive drive pulley, this way I can wood or metal with the saw. It has a 1.5 hp. motor.

I've considered doing the same with mine, but mine uses a toothed belt, and the motor is pretty close to the drive wheel, not sure I could fit a larger pulley. Mine's a 14" Grizzly, BTW. Works okay as is cutting aluminum, but I'd like to be able to cut steel with something besides my 4 1/2" angle grinder and cut-off wheel . Good luck.

upright metal cutting band saws, the main features that allowed them to cut hard steels and thick sections, were the motor/tranny torque and blade speed, for cutting steels the blade has to be moving slow enough that you can see the individual teeth while it's running. I was surprised that I had to go from 4"-7" on the final drive to get it slow enough.

I am surprised that going from a 4" pulley to a 7" pulley gets you from a wood cutting speed down to around 200 - 250 sfpm for steel. I would have guessed still not enough reduction.

and the saw was made for re-sawing and seemed slow to me for a wood band saw to begin with.

a 2" pulley driving a 4" pulley which drove a 2" pulley that drove a 4" pulley at the final drive. Now it's a 2" pulley driving a 7" pulley that drives a 2" pulley that currently drives a 7" pulley on the final drive. It looks like I have room to run an 8" pulley on the final drive. I'm waiting for blades to arrive so I can try it.

I did this conversion a number of years ago based on an article in Projects in Metal by 'cannot remember' Mclean?

Using a flex plate and starter pinion the bandsaw can run slow enough to cut steel. Made the motor reversible to save using an idler gear. Works great!
