5-speed swap
i have had the Keisler unit sitting in my garage for almost a year now. Working on getting a rottiserie built to do the body work and paint. Looks like we are in the same boat.
I would go ahead and get the hydraulic clutch setup and the Lakewood Bellhousing. It's bitching. Pretty red too. The TKO-500 is good for a small block up to 450-500 hp according to Keisler. The TKO-600 for the more beefy big blocks
I'll be running 3.23 in mine. should be nice at 80 too.
