727 or 904?

1300 to build a 904....nope....probably got less then 400 dollars in them...minus the valve body....24 spring is a one time expense...
904 does not need aftermarket drum...Never seen one explode.....
All 3 of our cars use stock drum..stock disc and steels...yes...24 spring kit is 120 bucks...single would spring in opposite direction from ATi is 20 bucks...

As someone says...pick your parts and spend your money....and do whatever lets you sleep at night..
