@csx4910, These conversion's on 240,260,280, and Rx-7's, are a hoot to own & drive. I spent a couple years looking for just the right one. Found a 86 Rx-7 (Built by a Boeing Engineer) with a built 302 Roller Rocker (350-360HP), and a T-5. Mine is a sleeper, quiet pipes, stock wheel's, etc. But you nail it, and it go's up in smoke in the first 3 gear's, the look on the Honda, WRX, Nissan, etc. guys is worth the price of admission. Surprised a Vette or two
Even my hot-rod friend's think it's pretty cool. It's a keeper for sure. Good luck with your search, Get a S-30 series Z while you can, they are bringing BIG money now.
