So I dyno'd the 97 tonight...
The numbers don't look very good...even though mine hasn't been dyno'd I would get in the 280-295 range. What town do you live in, and is the dyno place you were at any good?
And as far as the numbers, I figured since GM rated the car at 285, and figuring in the drivetrain loss, 234hp/269tq is pretty dead on. It's stone stock, remember?

Our cars are RWD....but I'm assuming it's a typo

The numbers are probably dead on for the condition of his car, but I have honestly seen stock 97 Formulas dyno at 265-270 RWHP.
How much did they charge you for 3 runs? Is it auto? How many miles are on it?

That Richmond Performance Musclecars site that you have in your sig. I used to visit their forums but I don't know what happened to them.
