Re: difference between power and manual master cylinder
i do know that the cup in the piston is deeper in the manual one so the pushrod won't fall out. i did this conversion on my camaro and that was the main difference. as far as the bore size goes the larger one will push more volumn compared to the other pushing more pressure which i think you need the smaller one for pressure since there isn't any assist. i may have that backwards.
