OP - sorry for the hi-Jack.

The Hughes Performance 25-1 is their 1991-1995 case with 750 horsepower rating and is $2447 + $500 core charge via Jegs. When I spoke with them directly they said it’s actually rated at 800 hp. It looks like a brand new trans with all new components and updated cooling mods done. A dyno sheet is included with the trans. After placing my order all other communication was via Hughes Performance and their customer service was great.

As Jason mentioned, no trans tunnel mods needed in a 69 Firebird, only the banjo fittings. https://www.jegs.com/webapp/wcs/stor...0002&langId=-1
