converting to a C-4 or PG

[icu812]

I'm in the process of converting the Ol'girl to a C-4 or PG- B-4 I delve head deep into it are there any special "black boxes" I need to buy ? who makes is ? the reason I ask is I already have a PA super compC-4 with a brake and their Pro Mod Glide and a couple of Neal Chance converters laying in the garage and my clutch need replacing

If your sig is correct, you have more than enough tranny in the PA C4.

When you put down over 1000 rwhp or hit an 8 second E.T. and begin grenading the PA unit, start thinking about the glide.
