Engine Swaps - What about stopping?

["Robert J. Snyder" <rjsnydercpa@email.msn.com>]

I always read with great interest the discussions regarding engine swaps for
TR-6 and Spitfire.  I have a Spitfire 1500 that I was thinking of upgrading
with a GT-6 motor.  I was also going to upgrade the vertical link and brakes
from a GT-6.  However, I was wondering with the larger increases in
horsepower: V-8 in TR-6 or V-6 in Spitfire, what break modifications have
been considered and are acceptable?

Thanks,
