Bob, both Kiesler and Gear Vendors are a bit pricey IMO, but still the best solution to keep the power. Look at Gear Vendors this way.... I think, if I read them right. Instead of a 4 speed you'll theoretically have an 8 speed. You could use the Hurst T-handle with the button and have a pretty good looking setup to switch the od on and off.

My 79 Formula Firebird had the Pontiac 301 rated at 150hp. I'm sure the larger engines had 200 + hp. Not sure what the 403 had tho. 6.6s didn't have the hp that the 6.5s had from the 60s. You know the Feds, they made everyone cut the hp back in the 70s and 80s. Only now are we seeing the big hp cars from Shelby and Ford, plus Chrysler's new stuff. But anyways, the new cars today are lighter and their little 4 and 6 cyclinder engines are spitting out more hp than our old 60s motors. Kinda sad if you ask me.
