What is your budget ? Is this a max ET effort car ...or something that you are going to run 500 passes a year ?

The absolute MINIMUM I would do is an aftermarket alum or steel front drum. A heavy car - steel. Lighter ? .. alum.

IF you have a uNlimited budget .. you can throw the kitchen-sink at it ... and buy everything. Rollerized, straight-cut, low gear, etc - ETC.

But that bolt-in-sprag ...... unless your case has had a spun-sprag in it ... is throwing money away.
