340 lifter bores bushed or not ?? Solid Roller cam

For ever inch of circumference of your cam lobe a .750" roller will roll .15" more than a .800" roller will to cover that 1". Each turn of the .750" roller is covers 2.36" the .800" wheel will cover 2.51" for each rotation.

That’s assuming the same sized base circle correct?

What do the numbers look like when you compare a SBC sized base circle to the same lobe with a SBM sized base circle??
