How modded are you vs. him? How well does the SHO run vs. your car?
Stock for stock and same skill behind the wheel, I strongly believe the 89 SHO will take you in a straight-line race. They were the lightest and fastest of the bunch (I know as I had one that I modded up).
The Yamaha 3.0 V6 is still one of my all-time favorite engines. They just get better with age and they are damn-near bulletproof, unlike almost every accessory surrounding it in the engine bay.
